DHTML layers usually have the same effect.
In my own little world, pops aren’t really worth the trouble. (Yes, I have sites with pops for various reasons, even though I just said that.)
Here’s what I want. User clicks a search engine results link. User decides my site is credible. User clicks an offsite link and goes to a sponsor. If they don’t like what they see, I hope they hit the back button and try again.
I want one pageview, one clickthrough, and hopefully one sign up. A pop distracts from that goal, imo.
I know there are many here who have built communities and want pageviews and return visits. It’s a profitable move for many. I just don’t like the maintenance involved. I’m a search engine person, not a moderator, not a community builder. So, I’m not really advocating one approach over the other, just working in a manner that fits with my strenths, weaknesses, and dislike of constant monitoring, updating, etc. I still have constant work, it’s just algo based instead of socially based. It makes it easier for me to disappear for a month or so if I feel like it.
I do think that’s a good idea for fraud monitoring. But, how big is your bat? A “guarantee” might not be the right word to use, since it’s often difficult to figure out what a situation actually is. People lie, all of the time, on both sides. There’s certainly nothing wrong with you working toward being a problem solver. In so many industries, people who figure out ways to solve problems wind up wealthy as a result.
