I feel your pain man ...

Even though you're 100% right i'm afraid your one-man-protest isn't gonna change all of this. In the clean section even 80% of all links are sexually suggestive. Converting them all to clean would generate ann xcess amount of advertisers in the adult section and not enough in the clean section, (I THINK) . Sex sells, and that's why most of those ads are referring to sexual websites. And i also guess LB's definition of clean is somewhat different than yours, meaning they describe adult as 'visually' explicit (as in nipples or genitals would totally shown), not 'verbally' explicit nor sexually suggestive. I too feel there's a thin line between those too, and I would find it a very nice achievement by LB if they could filter those out. But I'm not striving for this, because I know LB will have to do alot of financial changes to get this through, and abviously i don't want LB to have financial troubles

. But i do get your point and i can relate to it.
Good Luck !!!
