Strange sites open from ebay pages

it is some days that strange sites open while I am working in ebay, for example while I am browsing listing from my ebay pages. When I click on link, another safari page opens on its own. Does it ever happened to someone else? This just popped up suddenly, I suggest you to do not visit it, it is just to give an idea of what is appearing:

What the hell is that? Have you got any idea?? Dangerous site?

Thank you for any suggestion

This was most likely a kind of popup window triggered by an ad on the eBay website.
I can’t tell if it’s a dangerous site but I guess (and I hope) that eBay checks what they’re showing on their website and they don’t insert any fishy ads…

Hello Kristian,
I don’t know what to think… I don’t know how it works there, but here ebay site is becoming to be unusable at all, one of the weakest site I work on… and the most I pay… !!!
