wagerx.. apologies,didnt say it correctly.
It isnt malicious, but sneaky when some affiliates do link exhanges with other affiliates. Some affiliates will do link exchanges using this javascript method.
What this does is make sure that the bots dont follow through the links…
As for a user clicking on the javascript link, thats fine, nothing malicious there. Although I prefer to use this an alternate method, rather then having straight normal links to the advertised casino, an alternative is using php, where your link could look like
http://www.wagerx-website.com/linkto.php?gotocasino=casinoid
further.. if the user did copy and paste that link into their browser.. it would still send them to the casino.. with your affiliate id attached!
