.ru domain spoofing slappin the sh^t out of my servers

Recommended Posts

Anyone else getting beaten up by registrations from russia ?

 

At a glance on one site I've had 5000+ in the last 24 hours. Logs don't show any more than normal port mappings and root attempts, just registrations like sadly madly.

 

They seem to be doing this from a mail server ----

Most of them probably aren't actually in Russia, just tunneling through there.  So don't be pissed off at Russians.  lol. Be pissed off that Russia doesn't do anything about it... so people use Russia as a gateway to mess with people.

 

 

... I haven't had any problems since I changed to keycaptcha on registration.  Way less registrations, but they're all human.  I was so impressed with it after just a couple days I paid them for the full version.
