The 20 year olds' nickname, "Dime Piece", means $10 whore in that community.
There were other girls there to whore also. They are listed as "Dime Piece Girls". The youngest is 14.
Please note that this "pool" party was meant to advertise a bigger, paid-entrance party at a later date. They were handing out flyers for it. It was entitled "make that @sss slap" or something similar.
The "Conservative Treehouse" certainly seems to find out additional information in these situations, and I cannot fault their investigative efforts.
They have added "the rest of the story" many times on various other events, and I consider their analysis to be quite good.
