I have not used it in years but that doesn't mean it's not good for others.

P411

Good  screening platform for everyone , clients will find reputable providers.  VIP here on TER also answers a lot of questions.  

I found it helpful when searching new cities while traveling and that is helped streamline screening to some extent.  Before booking anyone I search here, there and make sure someone's presence is consistent across platforms.

Did you used to have an account? If so you should reach out to admin there and see if there's a way to get your profile back if you re-join.

 
I have been a member since 2017. If I knew then what I know now I would have paid for the lifetime membership.  

 
It's true that these days more providers require real-world info for screening than a few years ago, but I've found my P411 membership to be very valuable. I've rarely encountered a provider that I've wanted to see that didn't accept it for screening, even if they were not members themselves. Obviously everyone can have different experiences but for me it's been well worth it and it saves me a lot of time and effort in meeting women.

People still use it but it isn't as favored as it used to be, from a provider's perspective. Fewer accept it without some other form of verification. A lot of girls don't even list on there. But a lot of sites are like that. Things started to get more decentralized after fosta and it's been trending in that direction since

Bit the bullet a few years ago and paid the lifetime membership fee after being on there since 2014; beats paying every few months and has been an invaluable tool. I recommend.

It's not as big as it was previously, but it is definitely worth getting on there as there, as there are still a few clients who primarily book through there.
