Lemmy.world removes its rules against discrimination

Unless you provide the exact text you were banned for, I'll be having my doubts.

Was this during the sync thing?

To be honest as a mod or admin I would personally get sick of reading the same things over and over again, with sync fans attacking staunch FOSSers and staunch FOSSers attacking sync fans. It only served to get both sides upset for literally no reason, and fracture the community even more.

Their inboxes would have also likely been flooded out to death during that time with both sides reporting each other over petty remarks

Doesn't make it right, however I can see why it happened. Probably another reason behind the "dont report something unless its against the terms" rule.
