>>I for myself hate site doing popups, popunders and so on.
Cheering in the background!!!
<warning: useful information, but expressed somewhat emotionally. You might call it a "rant">
I have some personal standards about sites I accept. I do not accept sites that do popunders. End of story. I hate popups, but at least they're obviously associated with the site I'm visiting. But popunders and exit popups -- I despise the attitude that says you can do something you know most users despise, so long as they don't notice until after you're gone. (It's like saying murder is bad, but a drive-by shooting is all right.)
Now, that's not generally the ODP standard (BUT NOTE WELL--SOME CATEGORIES DO HAVE SOME SUCH STANDARD!), and so when I refuse to list such sites, I don't delete them either. I leave them with a note saying something like "inflicts popunders on hapless visitors" for someone else to review....later, perhaps much later....if they have a stronger stomach.
