Today I noticed when I click a link a user has posted, it goes through a URL called "webgains". At first, I thought just one user did something odd, but now I see it's any link anyone posts. The link looks normal, and it goes to the site intended, but first goes through this webgains. So I looked and webgains is some affiliate program and I am wondering if someone hacked my site and added their own affiliate program to make money off of my site?! I certainly didn't add it. I only use Skimlinks, and I don't believe it's affiliated with webgains from what I can tell. Of course I notice this Friday after they are closed for the weekend and they have no email support on their site, only telephone. I tried to check for an account under my email but there is nothing. I want to shut this down ASAP but don't even know where to start. Ideas of if this could be some hack or where it is coming from?
