Yeah, keep it in seeking services a bit until you are comfortable with the new persona.
I have done the re-inventing thing a couple of times over the years, I have never collected that much feedback though (think the most was 28 or something). Every single time I have done it the reason has been because I have changed my services - I have went from quite extensive services, to very very tame services which prob wouldn't even be classed as sex work (!), to the middle, to more on the tame side again. Or because I wanted to shake off some less than desirable regular punters or persistent callers in my phone - you do need a new number for that though. I decided to make a whole new profile, pics, phone number etc when I changed my services because I wanted a clean break - so no clients could complain of "oh but I saw your profile a month ago and it said OWO" etc, or those that contact you over and over but take ages to book could eventually book and expect a different service. Also it made returners less likely to badger for services I no longer offered if i was on a new profile, name, number whereas if it was just a little note at the bottom to say something had changed, I expect they would still assume the previous services were ok.
I don't think it has much to do with a bad reputation - most clients don't put all that much thought into it to be honest - they don't search reviews in the main. I've had "bad" reviews (but many many more positive ones) and I can categorically say it made zero difference in how busy I was or not.
Once I changed for a legal reason.
Also, some ladies are not too keen on being "known" - I am one of them I guess.
Go for it, I don't think it will make much difference but if it makes you feel better in yourself I think it's a good idea.
I do agree with the poster who said that it's difficult to charge higher than average rates (not saying you do, just in general) when you have less than say 3-5 feedbacks.
