I doubt very much if agency girls or independents move in concert.  This is a dynamic process, and while I couldn't even pretend to know the answer to the OP's question, I think that they all come and go according to their individual needs and desires -- and some agencies disappear then resurface under a new name, and so on.  So, as people come and go, we have no choice but to be patient.  There is also something to be said for the continuing numbers of new faces, which seem to me to be increasing.  My own preference would be for some of them to stay around a little longer, but I have no say in the matter.

The answer is simple my ignorant friend: LE is theeeeee MAIN reason.

Any agency would want to stay in a particular area if the money is good. However, LE, well, they ruin it for everybody around here. By the way, it hasn't just been "in the last week or two", but in the last few months. Check the threads for the records, its all there.

I agree with "noagenosage". Agencies come and go. Some will resurface under different names. And, the best we can do is be patient and wait. Kinda like I'm always waiting for my none employment check, early social security check (I complained that my back hurt), and all of those damn free government handouts that I file under pretense.

Oh, since I'm here, did anyone wrote to TER to inform them that misspelled a word in their front page for their new 1 million review giveaway? Can't remember which word it was, but they should correct that misspelled word.  

Good day to you too my ignorant friend. Bye! And, see you around town, LMAO

Au contraire, mon frère

Plenty of beautiful ladies coming your way soon, patience!
