A year ago, FB gave me a 1 month ban, then at the end of the month, said too much time had passed to change their mind, and it was permanent. Before all this happened, someone was looking at my postings 6 months earlier, and started to report them or complain about them. I don't think any of my FB friends were scrolling back to look at my postings in the past. Someone was getting paid to do this. When there was a button to object, I clicked it and sometimes the complaint was removed.
