-1No punishment required.
Having seen the evidence, I do admit that Vector does ban people without a good enough reason.
Having saying that, I do believe that "Other" was a mistake. Also, I would like to say that Vector does his job and keeps most of the people on the servers entertained and happy. He may ban people for the wrong reasons, which he needs to work on.
Another thing about what Hachi said, "Someone would have made an abuse thread a long time ago".
Vector may also think that he owns the server, but that, my friend, is dedication to making the server as good as possible. If he wants to get rid of some players because they are mic spamming, rule breaking, or generally just being a douche, so be it; it's for the server and to actually make it fun.
Finally, as of Maymalays' evidence, check the date of Gorillabot's "Hello and goodbye" post. It has been more than two months that that post was created. Have things changed? Maybe they have; two months is a long time.
However, this protest does show that Vector needs to be careful of what he does; I do not believe any severe action should be taken - this should be just counted as a warning.
