I have not dealt with this agency and as of yet and am not sure if I ever will but I have noticed alot of criticism of them on here, fair enough everyone is entitled to their opinion and perhaps the critics of this agency are correct.
But I have to say that there coming on here and engaging members in dialouge is a plus for them in my book. Not sure if you could judge them as legit because of this but very few scammers get on the boards trying to convince people they are real - they usually scatter like roaches whenever a light is shined on them (i.e. take down their backpage ad and post another in its place with a new set of fake pics.
I say give them a break and sit back and see how things progress, the truth should come out in due time whether they are legit or not.
