I normally block and remove them. This one, to keep the thread meaningful, I simply blocked him. He can't log in again from the same place or same email so just as good.
This is one that slipped through the automatic checking system we have which is still filtering out about 20k attempts a day IIRC.
The best thing to do if you see something like this which looks out of place or just plain spammer is to click the "report" button and it'll send me an email. The less airtime these arses get the better.
