I've found that greylisting takes care of these mining attempts anyway.
Sure, my greylist database is filled with rubbish, but at least it will be
cleared in 5 hours' time and the mining attempt would not have got a single
username right, unless it was re-run 30 minutes later. With the distributed
nature of these mining attempts, that is rather unlikely.
You may want to do greylisting for anti-spam purposes in any case - and it
also addresses this issue.
