Yep, that was one of them. Do you think that’s a good mechanism to automatically delete all user’s content when they get banned? Those example titles you shared don’t seem like obvious trolling nor obviously worthy of an account ban, and the collateral damage of deleting valid & popular threads seems bad.

There seems to be room for improvement in how Lemmy handles this.
