Is this a new site that girls can post ads on ...anyone know anything about this site

Sugarnights is one of many sites copy and paste escorts' ads and pics without that escort's permission.  Then someone from Sugarnights submits a problem report on TER to get the site added to the TER ID.  

I guess that they're trying to get a lot of clicks for ad revenue.  You shouldn't support them by contributing to their web traffic.
