I'll be honest, running black hat ads on tiktok today is extremely difficult and risky, the platform has an artificial intelligence system that scans videos, audio, and text for prohibited content. If it detects anything suspicious, your ad doesn't even make it to human review, it gets shut down instantly.
The most common method used to try to trick the system is cloaking, which involves having two pages, a normal one that the tiktok review team sees and another hidden one with the real content for users, but that's no longer the case, tiktok closed that loophole and now uses scanning technology that detects hidden code, if they find anything suspicious about your domain, they flag it and can block your account and even your funds, if you still want to take the risk, don't post anything for the first few days, then upload a single high quality video and monitor whether it gets any views, if you see it gets zero, they've detected you and banned you, black hat advertising today isn't just a gamble, it's practically account suicide. In these times, you'll most likely lose your investment, your account, or both.
