go.redirectingat.com hijacking ebay links

[wb2mep]

Why is it that all ebay links get diverted to a site called "go.redirectingat.com" ? I then get "redirected" to ebay listings for new crap instead of the vintage item mentioned in the post. Examples - In the vintage B&W forum there was mention of a Holland RF combiner for multiple modulators onto one cable, with an ebay link. Clicking the link brought up the redirecting site, which redirected me to listings for JBL ceiling speakers. And, a link for an ebay listing for a 1960 Zenith w/original box, sent me to listings for crap LCD TVs.
What's even worse is when I try to copy the ebay link to bring up in another browser window, the "copy" and "paste" options are grayed-out. Anybody know what's going on here?
