Mojo that link goes to another link you posted that leads to no real answer can you just tell us if we just have to deal with it (site is being paid) or if its something the site will fix (the pop up is malicious) either is fine but something other then a link.
Trey check it again. This question comes to this forum all the time and i redirect it to the same section each time. Its a site wide issue not local so the best place is the tech forum in the front page.
So in short as far as we local mod's can tell you there is nothing we here on the local level can do or tell you to stop it.
Maybe I'm a little slow, but that link takes me to another thread called "Eros Guide popup", talking about a similar situation that was going on last August / September.
Seems either the site been hijacked or it's happening with mod's approval.
I'll be blunt man, in this forum there's nothing we can do about it. That's a software/programmer issue which is why it's probably best you start a thread in the tech or member feedback forum.
