Hi,
I have trouble figuring the actual web domain for the token website ID under Popads. Is there a way you look up the actual website for the website ID token?

Not via popads dashboard.
If you start with category and use clues like time-of-day activity to gauge location and 101 other things you *may* be able to figure out who it is...though they're going to go out of their way to make it hard for you. Honestly would be a waste of time anyways.
Just look at how many people are targeting vice excluding and have your "popads list"
