There are very few that get away with it; most only because of the browsers security settings being loose, or because your site is carrying scumware.

There's no guaranteed way of creating a scum site, except by using scumware - but even then, most decent human beings can use software to squash your worst intentions.

Repent; however sad your life is, there's no need to sell your soul to promote it.

Just build a better site. Easier, satisfying, your friends will still talk to you, and your kids won't spit at you.

Much better ;)

Some years ago I ran a site for a music promoter. Pop-ups were an excellent tool for highlighting important changes to previously published information when performers pulled out or venues changed at short notice. It is a shame that the scum sites abused them and brought them into disrepute.

These days with blockers so widespread I have no idea why people still use them. With blockers both in Firefox and in my firewall I have almost forgotten what they look like.

That reminds me, I have to rethink aspects of my site navigation. I went out of town recently and saw my site from a few different computers. A lot of basic functionality (e.g. image zoom) uses "popup" windows, which are getting blocked even though they are explicitly triggered by an onClick event.
