here's my research thus far
i searched up those IP's in my connection logs, and i actually got some people who have those IP's who connected to the server before. let me list them.
98.143.8.253 IGN: Munchma Quchie BLID: 54176
(space for dramatic effect)
98.193.194.128 IGN: Custardo BLID: 36715
so the person that could be doing this is fen. honestly, i'm not too surprised.
