Fans complain about spyware on wrestling sites

Indeed, wrestling fans have every right to complain.  I'm aware of several wrestling sites that are chock full of spyware and adware, sometimes installed with no notice or consent using exploits.  In fact, several of my fellow spyware researchers (and zealots) have used wrestling sites to look for new infectors and document non-consensual installs. One such site was active for several years but has been inaccessible for the last few months.  The site's homepage appears to be password protected or perhaps blocked to certain IPs with a .htaccess file.

There is one website which I will keep anonymous that not only used that popup ad to induce "memberships", but they have now added spyware. And they are actually telling fans via emails that they know there is malicious spyware being installed in your computer without your knowledge. Their answer to resolve the problem? Subscribe to their Ad Free Website.

The writer's advice:

Just remember. You should NEVER be forced into believing that you MUST allow spyware to be installed in your computer [...].

I'll second that. 

Why do wrestling sites use spyware? Surely there must be better ways to pay the bills. Another group of sites known for spyware is music lyric sites.  Surfers beware.
