[Question] FB Ad Accounts Pausing / Spending Drops After 3 Hours – Daily Pattern

• New creatives or recycled ones – same result
• Clean cloaked landers or direct offers – same
• Warmup vs no warmup – same
• Even across different business managers and IPs

Hey guys,


Been running into a frustrating issue and wondering if anyone else is seeing this.


Every Facebook ad account I use – whether it’s personal, BM, or on a credit line – starts off spending normally when I launch a new campaign. For the first 2–3 hours, spend ramps up fine, everything looks good. Then suddenly... it drops to a trickle. No hard stops, no disapprovals, no bans – just super low spend for the rest of the day.

And this happens with USA target only.


This happens every single day, no matter what I do:

• New creatives or recycled ones – same result
• Clean cloaked landers or direct offers – same
• Warmup vs no warmup – same
• Even across different business managers and IPs

Doesn't matter if it's a personal account, a verified BM, or a trust-tier line with FB Credit – same 3-hour "sweet spot," then spending basically dies.


Anyone else experiencing this? Is this some new FB learning phase throttle, risk flag, or algo behavior?

I’ve seen a similar phenomenon recently, especially with traffic campaigns in that market. Spending is stable for the first few hours, then drops off dramatically without any warning or obvious signs of violation. I’ve tried a number of options, including hourly budgeting, changing campaign structure and creative, but nothing has improved the situation. It’s likely a new control mechanism related to spending behavior or account signals, rather than technical or content factors.
