We are obliged to wonder what this "viglink" is. There is a wikipaedia page about it here https://en.wikipedia.org/wiki/VigLink
It is "a San Francisco-based monetization service". Is that not a source of delight? It also provides "an outbound analytics service for clients to understand where readers go when they leave their site"!
Well! If one looks at the Proboards support forum one finds that it is all about "revenue" and many people are complaining about the theft of bandwidth. I am not happy about it; but what do our other members think?
