First, this forum is answered by the community, not the staff.
Second, it seems the automated anti-scam filter has flagged your posts as suspicious. To clarify, this doesn't mean you did anything wrong; it simply means the automated system detected something suspicious, and your posts must be reviewed and approved by a human first. The best course of action is to contact Itch support, explaining the error message and what you normally do (posting links to YouTube videos where you share gameplay of those games).
