Agreed - but making one up should be ok. If you really need to wait until someone checks every possible poster ever on Perb, then I suspect you will be wasting your time on someone anyway.
Making one up FOR FUN would be OK by me, if that's your thing. This hobby seems way too serious to some folks- a little levity now and then is good for body and soul. Maybe use "PANTIESNIFFINDAWG1" or "FVLOVER"? Oops- sorry- those were already faked and banned- my bad!
Of course, said SP would probably get pissed when she figured out she was wasting her time when searching for non-existent research data and cancel your ass- but of course from your point of view would seem to be no big deal. All in good fun, right?

I'm not one to succumb to a screening process in order to get some action. I have never booked a session with an SP and claimed my handle beforehand. If I can't set something up on my own truthful merits- which has NEVER been an issue- then I would simply move on to another. Of course, there are exceptions to every rule and there might be one or two ladies (who shall remain nameless for now) that I might be inclined to relax for.
Yes- I have shared my handle with certain SPs after the fact if a very comfortable rapport has developed. But only at my discretion. And an SP reading up on my postings has never impacted future visits. Truth be told, it is rare that my SPs even ask if I'm a Perbite- occasionally yes, but rare for sure.
And I have also had PM interactions with certain SPs- but not to book sessions.
Maintaining a certain amount of anonymity is important to me- and most others from what I can read on here.
Doesn't mean I have anything serious to hide- certainly not my posting history.
If an SP reads my posts and takes away that I'm a real sarcastic bastard A-hole then so be it. And if she chooses to put me on her "list" because of it then so be it.
But doubtful that she would know me as ddcanz were I to show up at her door.
"Reputable" handle? What does that even really mean?
