He basically requested the ban.
He said he'd scamquit, he then made a thread asking the community what he should do to get banned (which rule he should break).
He made 11 spam threads in a little over 2 hours.
I tried to be nice to him & tolerate it, but he seems to be a bit too immature these days, so his ban will be staying this time.
