This is tough.
I don't like banning people who have been contributing for a long time, but in the span of a few days he's been suspended, trolled moderators through the report function, and circumvented a ban. And our rules are pretty clear that circumventing a ban will lead to all accounts being banned.
If you want a clean answer I lean ban. But if you're feeling generous, I'd also be OK with giving him one last shot to ride out his suspension, and if he tries to circumvent it again he gets the boot. My short answer is yes - ban.
