"This ID has been deleted or blocked from connection." HELP

Erhm. :/ My boyfriend can't log onto his account because of the this error...
I assumes he got banned, but what was his offense?
I've asked the GMs and they've only said to wait for the restart, and we've done that, so what would be the next step.
Please help.

His ign was: Exilement
This is QTpie.

[GM]Ally banned Exilement: botting ;

Tell him to post a ban appeal on the forums.

Eeeek, thank you Danny. ^ _ ^;
