What's up with "Worker is temporarily banned"?

First I had trouble logging into the site because account was suddenly banned.
Then I tried to reset the password and that didn't work.
So I figured I'd use the contact form and ask for help but that didn't work either.
A PM here was the solution and I finally got access, only now to have my worker banned.
With a banned worker my cgminer (3.7.2) keeps on trying to mine and won't change to a backup pool.

Not at all welcoming and easy to work with this pool I must say.
