I run a business and got my Facebook account banned in a trip to Japan. I genuinely was devistated, after getting rejected, reaching out to Meta Verified support and hearing there was nothing I could do.
I had $750 in ad funds as well, which just got absolutely evaporated. I was also using my exs account in the meantime to run ads (you can imagine how scary it was to wake up with everything gone).
I sent a small claim to Meta after reading a bunch of posts here. I just logged in today as I tried to make an alt account to see if it would work, I accidently logged in with my old Facebook acc after selecting the pre-filled login information, and it's just unbanned! My funds are there as well, and I believe it was because they saw they got served. I am very surprised because I got no email at all about this, it just happened.
I know how much it fucking sucks for this shit to happen, so if anyone wants to know my method please dm me. I might just write a guide about it.
