Stop The Proxy

[jonsavvy]

Does anyone have any idea on how to stop proxy servers.
While I respect peoples desire for privacy - a huge number of proxy servers are displaying my site, with my ads blocked, and then using their own ads on it.
Other than a legal solution, there must be someway of stopping this.

depends on how anonymous they are. if they're 100% anonymous, i don't think you have much to do - maybe only test the ip's in a proxy database - not sure where you'd find that, especially that they change so quickly.

BUT. for the less anonymous ones, the "HTTP Forwarded For" IP information should be different than the "host address" IP. you could have a small script to test that and if the values are different, block the access.

to see what i mean, try to use a non-anonymous proxy on http://ipid.shat.net/ .

this could reduce the number of your visitors though. some companies and even ISPs use proxies.

Doesn't AOL use proxies too?

Well as a free content site that depends upon advertising for survival - blocking proxies that block ads isn't such a bad thing.
We are pop up clean, and i don't believe intrusive to our readers.
It is an ongoing issue, as you are right I don't have problems with public proxies, it's sites like - www.proxyking.net which are guilty of stealing then re-advertising sites

Question, how do you know this is happening? Could it also be browser plug-ins killing your ads?

There are two things can do.

1st each visitor would have to have Active Scripting Enabled in their browser, just like when you log into your hotmail account.

2nd you would need to test for a proxy, like they conduct here: http://all-nettools.com/toolbox

Even after you do these two things, a highly anonymous proxy can still bypass detection.

Your ads are based on Javascript ? If so try to do a java script test before each page. and if the browser dosen't know javascript then redirect to a error messages something like this: "This site requires javascript. Please enable that from your broser and come back". And probably 90 % of your visitors will skip the proxy for your site or will enable javascript through proxy. If you want to know how to test for javascrip just folow this link : http://www.w3.org/TR/REC-html40/interact/scripts.html

Is something like that:

<noscript>This site requires javascript. Please enable that from your broser and come back !</noscript>
