Having had a pulse of the industry since 1996 at one point with 1500 members you know where, big changes happened after the DD raid where much of the evidence in addition to a book full or reviews was the undercovers at the parties who openly solicited and were solicited.
Today we have even more LE activity and felonies charged often.
Some of the private group folks (the boardroom) went to prison with felonies or pled to felonies.
In my view parties can be safe like the old Rose parties we co-sponsored with, or the "Sky High Condo" parties which was organized, presentations, intros (I enjoyed being MC) not just meet at a bar somewhere between 6pm and midnight and often a bit clicky.
Parties, get to gathers etc can be perfectly safe - dah just like anytime never discuss sex for money and of course don't work together with a driver or another companion since you may face a felony vs a misdemeanor. The easiest bust of course is for bad words like GFE on ads or websites.
Compared to what many companions do all the time to be easy targets parties, meet-greets are far saver than most other activities companions do if done right like Rose's annual Toys for Tots and of course our parties that had about 100 attend.
The out-to-dinner dates referred to I have seldom if ever heard of back to 1996, including when The Bachelor Beat was the primary advertising media
