I kind of curious, if Mods and Janitors would be willing to weigh in:
Are there any rules we have NOW that were not rules when e6 started?
Like, someone did something that was not against the rules at the time, and the then-mods basically thought 'In hindsight, we should have thought of that' when making it a new rule?
This kind of popped into my head when re-browsing the forum thread 'who was the worst offender in e621 history' and a user said 'this guy is the reason we can only do 50 note edits an hour'.
So my brain went 'I wonder if there any other changes/rules due to bad actors?'
