[Operators] Strange users

I have seen something very similar on my server. We had tons of accounts with 
usernames of what appeared to be md5sums. They had no contacts EXCEPT they 
were using our MSN transports. At the same time I also had registrations with 
usernames that were exactly 10 digits (i.e. 0123456789 at jabber.fsinf.at), with 
the same behaviour.

I figured this was a spam-problem and deleted all such accounts plus blocked 
their registration. Nobody ever complained.

To make a long story short: I think we have a significant spamming problem on 

greetings, Mati

PS: Just for the record, jabber.fsinf.at is *still* on the public list, 
despite the fact that it doesn't allow any registrations. jabber.at is still 
not added.
