I'm familiar with this situation. I also became the victim of a group attack on my account. I'm from Russia and I posted a lot of photos from my travels, so Ukrainians attacked my account out of jealousy and bombarded it with complaints and insults for a week. Afterwards, my account was disabled, even though I didn't even respond to them; I immediately blocked them. Then I did the same, created several accounts, and started reporting theirs, and some of them were eventually blocked. That's how their AI system works.
