Yeah, proxies and VPNs can be tricky. If they’re not solid residential ones, TikTok catches on real quick. The cheap ones or unstable connections? Pretty much waving a red flag. Also, if you’re getting junk traffic like bot clicks, that can mess with both your data and your trust score. Did you set up any filters for that?
How separate were your accounts though? If they’re sharing IPs, cookies, or even browser fingerprints, TikTok's gonna connect the dots. I know some folks use antidetect browsers to keep things clean. Makes each account look like it's on a different device. GoLogin and Multilogin are popular, but they’re kinda expensive. I’ve seen a few people use Hidemyacc too. It’s cheaper and seems to work fine if you set it up right.
And what about your ad flow? If your ad and landing page don’t match up, people bounce fast, and TikTok notices that stuff. You might want to tweak your targeting. TikTok’s ad system actually has more depth than most people think. I usually start small, like 30 to 50 bucks a day, just to see how it performs. If things still look rough, agency accounts tend to be way more stable and less likely to get flagged.
