Just to be clear: Friendship's ban is from constantly violating the rules. The leaders just want to prevent any more actions violating those rules, which could cause a lot of safety issues, which would be kinda creepy.
Liza's post also explains this:
As she mentioned, it's fine to debate, but note that she has been suspended before without change in behavior kinda calls for a ban eventually.
To be clear, the reason the mods chose 8 years is because it's virtually a ban besides all of the unlisting and flagged posts, because she has quite a lot of good posts, including her Hopscotch Awards.
Also, we do like Friendship (we don't simply ban people because we don't like them), but we do have to realize that she was breaking the rules a couple of times.
