I've seen/been through a bit of this:
- booked an SP on short notice who I offered my PERB handle to and after booking she commented she had read some posts and thought I was a good guy (thank you)
- first coming to the island from Ab and trying to make a booking I gave my relatively standing CAF handle and the name and # of an SP I saw..hell, 8 yrs ago as it had been that long. As I expected, the AB SP did not remember me ( one time, simply last one I saw) but I didnt know what else I could provide. I think in the end I might have shared a partial picture of my DL. Not something I was crazy comfortable with, hadn't done before but she is not the first..or last who has asked for this and I understand why. If I wasn't single I'm pretty sure I wouldn't have been willing to do that!
There is risk on both sides when booking an encounter especially those with no prior history. I think both parties should do their homework to the extent it makes them feel comfortable and is respectful. I can see PERB being one method. I doubt it will be the primary method. A positive experience with another reputable SP will win the day for most SPs I bet.
The other problems I see with using your handle as a reference:
- There is going to be lower hanging fruit available without an SP having to spebd time reading your posts. Text a fellow SP? Ask for a DL or deposit? Quick! Time is money.
- Maybe they can't even be bothered with these sites.
- Maybe they don't like your opinion or misinterpret your words. Too easy to take things written the wrong way in general.
Given the choice, as a client I'd prefer and I imagine an SP would too, for my good and recent rep to stand for itself. Just easiest and proof in the pudding.
