I tried, but seems not working.

 

will this php script help

 

You can use RBL/DNSBL for it It will block most of the proxy ip, even few genuine ip, but it might help.

Also be choosy with RBL, don't select very strict RBL like spew.

 

how to use RBL/DNSBL?

 

When using

it seems a lot of user been blocked, but they are not using proxy.

 

That's an old method that is no longer useful.

 

thanks for the reply.
So what's the new method?

 

I think that RBL usage is your solution. Using any methods won't protect you against SOCKS5... as you will never know whether it is a proxy or not
