Will agencies still be an option?  Will their sites get shut down?  Is it even safe?

No...I won't do biz anymore with an agency.. I have and loved it.... but when they get busted LEO has your info.. I'm still worried about the bust a year ago...

Their Ad page is safe and their girls are great.  Agency does a great job.  Girls are all GFE, but you have to earn their smile...it seems from experience.  I do have my favorites.  Only downside for me is driving/parking into Boston.
