I love P411. I always recommend it to respectful gentlemen. I do appreciate that P411 holds both providers and hobbyists accountable to certain standards of behavior and when a client contacts me through P411, I do tend to give those gentlemen booking priority. With P411, I can usually count on the clients to be serious and not be wasting my time, as they would get booted from the site pretty quickly if they were NC/NS'ing providers or something. Same goes in the reverse. Of course nothing is foolproof so it's no guarantee, but I find it to be a platform for facilitating what I would call "higher quality experiences."
In some ways it is like when you are a platinum/diamond member of a hotel/airline rewards program, where it sends the message that you are a serious client and just makes everything go a little bit smoother, makes providers more willing to accommodate, etc. At least that's how I see it from my end. P411 is not a screening service, just a verification site which is one tool in the screening process, so if ladies are complaining that security is too lax, it's my opinion that their standards might be unrealistically high. P411 is one of the tightest run ships in the business from my perspective, has excellent and responsive customer service, and also is transparent when the network is compromised in any way (like when infiltrated by LE, etc.). These events are rare and I personally would rather a site be transparent about these things when they happen so we can know about them. Most other sites do not send out site wide bulletins every time an incident happens, but of course, that does not mean that incidents do not occur... We are just not told about them. Integrity is important to me and the transparency is useful for understanding risk levels in certain geographic areas. Also, on many tours where my schedule is decently full from my own existing client base, I might ONLY advertise my visit on P411 and nowhere else, since I am only seeking a few more clients and P411 bookings are generally the lowest hassle and turn out some of the best gentlemen.
