Has Meta Shadowbanned My Business Manager for Conversions?

Is it possible that Meta (Facebook Ads) is somehow restricting my account from generating conversions?

I’ve spent over $50,000 on ads from my main Business Manager. Lately, I noticed that even when I run conversion campaigns, I get reach, likes, and engagement – but no sales.

Out of curiosity, I tried running the same product and ad strategy from a fresh Business Manager – and suddenly the sales started coming in like they used to.

Is it possible that my original account got some kind of shadow penalty or trust score drop? Has anyone else experienced something similar where Meta just won’t give you conversion juice anymore from an older BM?





Would love to hear your thoughts and experiences.


Thanks in advance

It's possible that Meta is restricting this without notifying you, or it's possible that your primary ad account has been affected by a negative signal that has built up over time, such as low conversion rates, complaints, or suboptimal pixels. While Meta hasn't made an official announcement, many advertisers have reported a significant drop in performance on older ad accounts. The fact that newer ad accounts are delivering better conversion rates for the same product suggests that the system may be favoring newer accounts in its delivery algorithm. You should review your entire pixel structure, audiences, and violation history.

It could be because your campaign has been running on your account for a long time and the campaign has reached saturation (has been displayed repeatedly) leading to it no longer being distributed evenly and the same campaign but newly run has better results because it is distributed from the beginning, so the problem of reduced spending and results not being as good as the old campaign is due to FB's campaign distribution algorithm.

Sometimes it is possible indeed. Shadow bans are real on most platforms. Theres nothing you can do about it besides trying to be cautious next time

You know, it’s not really about me not knowing what I’m doing – I’ve been running ad campaigns for 10 years now, and I always spend as little as possible, getting super low costs. But there were times – maybe you remember – like one or two years ago, when running ads on Instagram (Meta) was a nightmare. They were banning ads, banning entire accounts. You always had to keep backup accounts, otherwise all your work was gone. Later they’d unlock them and say it was a “system error,” but we all know that wasn’t really the case. Still, those bans left a trace on the accounts.

My current issue is that the account I use now is in my mother-in-law’s name, because my own account is banned – even though I always ran ads correctly and never broke the rules. Same thing with accounts on my mom, dad, sister, brother-in-law, fiancée – I had them all, and one by one they all got banned. And not because I was running shady ads or promoting something illegal. I honestly think it’s because my ads were too cheap. I was always getting costs as low as thousandths of a dollar per activity. That worked amazing for a while – and then it just stopped.

Here’s an example: I used a client’s Business Manager recently. I launched the exact same conversion campaign there that I had run on my own account. On his BM – sales came in, conversions fired properly. On mine – just impressions, basically no sales. Maybe one or two random purchases, but that’s it.

And this makes me think – honestly, this whole Zuckerberg thing feels like a scam. If I were in his place and saw someone running ads for dirt cheap, I’d “press” those accounts too. I’d give them fake impressions, useless likes that don’t convert – because who’s ever going to check if those views were real? That’s exactly how it feels – like Meta is screwing over people who spend less.

Then there’s the domain issue. I’ve got my old domain and also a new one I’m trying to sell from. I get visits, I get clicks – but remarketing doesn’t run at all. Meanwhile, on another Business Manager with the same setup, remarketing runs perfectly fine.

So here’s my question: since my account is performing like crap, do I really need to buy a new business ad account (I see they’re being sold here), or should I just keep creating new accounts under different people and start over again?

It’s possible that your original Business Manager has been flagged or limited in some way, which can affect conversion campaigns. Meta's algorithms sometimes prioritize newer accounts or different targeting strategies, especially if there's been a history of policy violations or low trust scores.
Some tips:

• Check account health in the Facebook Business Manager to see if there are any issues or warnings.
• Test with different creatives or audiences as Meta may be restricting certain types of content.
• Ensure your payment methods and account information are up to date to avoid any red flags.

If the fresh BM performs better, it may be worth gradually transitioning efforts to it while continuing to monitor your original account.

I’ve noticed similar fluctuations in performance as well. Sometimes it feels like older Business Managers get less traction compared to fresh ones, which might be due to algorithm changes or account trust factors.

Yes, that’s possible — Meta assigns hidden trust/relevance scores to ad accounts, pixels, and BMs.
If your main BM accumulated too many flagged events (low-quality traffic, disapprovals, bad feedback), delivery can silently degrade.
A fresh BM often looks "clean," so the algorithm rewards it with better conversion delivery.
It’s less about an explicit penalty and more about cumulative account health + trust history.

There will be good accounts with the same posts and the same way of creating ads, but some accounts cannot be effective.

The decline in advertising performance may be due to Meta quietly restricting accounts or the accumulation of negative signals over time, such as low conversion rates or suboptimal pixels. In fact, the observation that newer ad accounts yield better conversion rates for the same product suggests that the algorithm may favor new accounts. Therefore, you should review your entire pixel structure, audience, and violation history to improve the situation.

Yes, that's possible.

Yes, this is a known "burnout" or "trust score" issue with older BMs that have had policy violations or frequent ad rejections. Meta's algorithm can silently restrict conversion delivery while still showing impressions. The fresh BM works because it has a clean slate with the auction. You'll need to gradually rebuild trust on the old BM with strict compliance.

A drop in ad performance can sometimes be linked to internal reviews or the buildup of negative signals over time, such as weak conversion data or tracking issues. In some cases, newer ad accounts may perform better initially because they start with a clean optimization state.
To improve results, it’s a good idea to review your tracking setup, audience structure, and overall account history, then make adjustments gradually to help the system relearn and stabilize.

Yes, that's how Facebook's algorithm works. It's possible that ads on your old account have been around for a long time and are only targeting your old customer base, and that's no longer effective or has reached saturation. When you set up a campaign on a new account, machine learning will search for a new customer base.

Thanks for this

I'm also using an account from a business that has spent heavily and is still performing well and is healthy. If your campaign is a good fit for a new account, you can transfer your budget there.
