List Crawler aka Mega Personals is a complete cesspool in Washington, DC. Does the site have a bad reputation among educated, high quality men? Are the providers on there simply not what you're looking for? This line of work would be so much easier and more enjoyable if white-collar men used Mega Personals.

A lot of guys use but they are bargain hunters.   Many who use that site can only afford low rates.

Maybe I'm missing something but first you said it's a cesspool then turned around and said men should use it.  

Not so say that there isn’t a diamond in the rough advertising there, but I skimmed the family of ad webpages affiliated with it years ago and, no, I would never shop there. The vibe I got was that anyone who used it would be asking for trouble and run the risk of getting robbed, meeting a pimp, or catching something (a beating, a bullet, an STI, etc). Whether or not that was a realistic impression, just the ads I remember seeing gave me the impression that it wasn’t worth it especially based on the quality of most of the “talent” advertising there. If for some reason I only had access to those sites, I would quit the hobby, but that’s just me.
