Hi, Tom and Rejo. Same with me. Half of the abuse complaints I get are from Valuehost Ru. Because I run on a cheap VPS I don't get a reassigned IP. Therefore I always fear that my provider might lose patience and shut down my server. That's why I decided to block Valuehost's range 217.112.34.0/24 completely.
I also wrote to Valuehost Ru and asked them politely to consider that their own customers might like to use tor and to reconsider their policy for abuse complaints. No answer yet. I think they have an automated abuse complaint system and don't care much for replies.
Cheers,
M.
