Hello everyone.

During the last days/weeks/month I have to deal with a shitloiad of 
bots, register account after account on my domains.
I watched this and found out a good solution: They all register random 
accounts with a 5-7 username like

xio5edx at DOMAIN.COM

And they come from these IP Addresses:

94.75.112.152 	94.75.112.152
96.56.83.114 	webmail4.mbi-inc.com


I allready cleared this list from TOR exit nodes and random enduser 
connections, but these IP Addresses are the main part. I had nearly 15k 
registrations in the last month just from those addresses.
I allready wrote to the Admins of these domains/Servers, informing tham 
that there are bots on their servers.

Anyone else having problems with spammers lately?
