Persistent "Unstoppable" RMT Spam-Bot

[Niwashi]

... Of course it wouldn't eliminate it, but it would increase the time between character creation and spam pretty significantly, giving SE more time to ban their account.

A slight delay before their spam begins doesn't decrease the amount of it any. It doesn't give SE any more time to ban the account, because the requests to ban it don't start coming in until after the spam begins.

Also, does that stop the tell noise?

Noises for all types of chat log events (including /tell) are fully configurable. The only difference is that /tell has one of the sounds turned on by default.
