i got permaban 99% of my accounts initially early this year, tried to play it safe with a single old account by only visiting niche communities, but shadowban eventually caught up with my account. i suspect it was triggered when i tried to switch toa firefox fork+ a mod removed one of my comments in a niche sub.

1st thing it did is force you to change password then the ban was immediate. i suspect they were using the “change password” trick to ban people.
