To whom do I speak about removing HaloCE player from ban list?

Unless it was the modacity server you were banned from, I doubt anybody here can be of any help to you. Sounds like it was just some kid-admin who got mad that you killed him.

If it was the modacity server though, I guess Jcap?

Man I don't get the child admins these days. I used to get accused of botting in practically every server I went into but I never got banned from any of them for it. I mean, except like some noob's shitty listen server.

There's practically no admins who can ban you. It's most likely the aimbot autobanning.

Most of the servers that still have people playing in them have autobans for pretty much everything that's cheating/annoying.
