Because they serve as proof if you misbehave. Even if you edit them, admins and Fandom staff can still see the edit history. So if you ended up doing  something bad, they serve as proof. It's why we also (as much as it pains me) have not removed the transophobic comments some users from long ago left on the Andy page. Because we want other users to see an example of what not to do.
