The only IP’s you’re allowed to mention on ManaCube, are the ManaCube IP’s. Perhaps Disillusioning thought you were talking about these?
As
@milkified said, mentioning other servers and especially IP’s are not allowed on any of the ManaCube servers, the discord or even the forums.
If there’s been a misunderstanding, your friend can appeal it and the situation will be looked into. In future, please refrain from discussing other servers on ManaCube.
