Even when I open the link in an incognito window, I don't see this pop-up. Do you need to be on the page for X time to see it?

Second request in a certain period, I think. I opened this link twice. The second time I got the pop-up, which starts out with something like "We've seen you here before...". I just tried a third time and it did not create a popup.

As things go, I think they're actually handling that part fairly well.

Pretty sure it looks for an existing cookie to pop it up.
