Sometimes it is not possible to find if user is using Anonymous proxy. So i came up with some ideas:
Get IP of client, do reverse check and check if it returns a hostname and also get number of any websites hosted on same ip then it could be a proxy connection assuming it is website hosting provider ip. Store ips of hosting providers which allow proxy hosting and query them to check if IP matches and block them. So guys do you think this technique is possible or might work to some extent?
I know these are not best solutions. I m not a expert but a newbie, please do correct me if i mentioned something wrong or something is technically incorrect.
