Other than that, I don't really see what, if anything else I would do.

LE is unlikely to go after you/me for a simple solicitation charge that could never stick without corroborating testimony, and I am nowhere near dumb enough to confess to anything.

Oh yeah, I guess I would have to find a new agency.

One would be the classic, only use burner phones to talk to agencies.  A phone with no record to lead back to you means they can't find you to ask questions.

Also communicate with an email address not attached to a real address or name.

Doing those alone helps quite a lot and means you don't have much risk from an agency bust.

Most agencies are also pretty careful about storing information though and a bust should not yield much.

Don't speak to anyone about it. If LE contacts you get a lawyer and take the 5th.

New focus is on pimps AND JOHNS, and treat prostitutes as victims.  Based on the Swedish model where selling sex is legal but buying it s illegal.  Many states are adopting a variation of this and focus more on prosecuting pimps and johns rather than the hookers.  The prostitutes are treated as victims and have a lot of incentive to cooperate.
Follow the good advice here and don't leave any trails leading back to you.

I think a lot of girls on the west coast are still mourning the closure of SFRB. I was in the hospital when I heard the news and all I could say is "NO!" Not because I wasn't able to post there but the security I believed I had when I used them. I can see the affect of it being closed down. So girls weren't able to recover from it and had to find other means and some built a name for themselves so the closure hasn't affect them much. I think when you spend time with a certain company and they sudden;y close down there's a moment of mourning and then on to the next.
