the three were it's off-topic, it's unnecessary, and it's not funny, which I would all agree with and also add extremely disrespectful (also impersonation is probably against some ToS that i'm too lazy to look up but I think we've already given enough reasons to not?)
"Funny" can be difficult to get right, especially with people from many backgrounds, or from all different parts of the world. I definitely posted (and sometimes still post) my fair share of cringe, but it's important to do it in moderation and try to think things through first.
