tons of registrations (usernames *[email protected])

Hello all,

starting 1 1/2 days ago we got tons of in-band registrations with usernames
like [email protected] plus some registrations like
[email protected]. Registrations come from very different IPs
from all over the planet. About 250 registrations so far. All these
accounts have username = password and are online right away. I allowed
myself to monitor some of the accounts and noticed that they send empty
messages to each other.

What is going on? Spam attack or botnet? Is someone else experiencing these
problems?

I'm finally really thinking about turning off the (besides to that) great
feature in-band registration...

Regards,
Martin
