I advertised some masks my grandma has sewn on FB. It was ok, expansive clicks like always but ok. This was running for at least a week or two. But when I changed some text it triggered a new ad review and within no hour my account was banned. It didn't even took a hour to deny my appeal as well and my account was lost forever (without ever naming any reason)
This account had 50+ (harmless) groups with way over 100k followers as well as a few thousand dollars in ad spend just that year. I didn't socialize at all on Facebook which I guess made my account fishy to some degree but all data was correct and passport verified.
This is the reason I completely ignore Facebook and all its platforms for whatever reason these days. I don't care if it could help my business, it's not worth the trouble.
