I guess a lot has to do with your place of residence, and how much you fear prosecution... and where your traffic is from...

I think in general it's a good idea, but for traffic flowing from one adult site to another I find warning pages 'a waste of space'. SE traffic most likely would be coming to your main tgp page, too, since that's the one which gets regular updates. But the old-fashioned set-up with Warning - Full Page Ad [- another full page ad] - First Content certainly has some advantages, and keeps the law enforcement away. You won't believe how many sign-ups this one full-page-ad can create, even on an established site with majority bookmarkers (it's my second best source of income - after my main page).
