I do not see the name Zeallous on the ban list for TeamSpeak. Is this the name you were under when the ban was placed? When did your ban go into effect? Were you in TS when you were banned or did you return to find you were banned?
As for the text he is believed to be receiving, it looks like he is attempting to join the server under the name TeamSpeakUser, which is a banned name. Please set up your own profile TS name so that it does not use this default banned name of TeamSpeakUser and you should be able to join.
See the following threads for additional information:
I changed the reason for the ban when players use the name TeamSpeak User - we are very limited in the number of characters, so the reason now says “Please change your name so that it matches your in-game name. - TSU”. Hopefully having the - TSU after the reason will help differentiate between the TeamSpeak User name ban and others.
