Excuse the O/T post, but many on here (me included) have found that over the last few weeks, whenever you click on a link in someone's post, it redirects you to a Viglinks site that has links for Walmart, Jet and the like. It was so annoying because you couldn't see what others were posting about.
In any event, I just discovered there is an opt out, which can be found here:
