Geo Information IP Address Host Location A1 A1, Anonymous Proxy City -, - - Organization Road Development, LLC ISP NTT America AS Number AS2914 Is there a way to detect and anonymous proxy on a forum? Then disable certain features if it is anonymous? Just a general idea would suffice.
Sorry, but I do not understand your question? Do you want to stop people from visiting your site through a proxy? Or do you want to stop them by registering through a proxy,,,,,? What is it "exactly" that you want to do?
We've had a few spammers signing up and PMing people. If I could detect the people that sign up through proxy somehow I'd like to put them in a special group that has PMs disabled. I don't know anything about these types of things.
During serious spammer / [****][****][****][****][****][****][****] problems I will block proxies, yes. It's fairly trivial - just check for open port 80 and for tor-exit hostnames. The former I prefer to just flag, but there's no reason to be signing up through tor.
