unless you've been naked, in a room alone with him, conducting an illegal sexual act where you are particularly vulnerable... Then, no, my dear.

We don't let the bros vouch for each other. I'm sure if you told your ATF that he was cool, she would take that info along with all the other screening information she would gather. If he passes her screening, great for him! But I highly doubt your referral would play much, if any, role in her decision.

There have been many cases where people were stunned that their good friend turned out to be a rapist, a sadiist or a pedophile. You just don't know what someone is like BCD.

when you ask us what other providers would do.  
I would accept that as a form of screening but i cannot say what most providers would do.

It wouldn't be the deciding factor, but it would sway the odds in your favor particularly if I know your and his real information.

For me...

I would accept that as PART of his screening. I wouldn't just see him because you said he's cool. A lot of girls see guys who don't have provider references, they jut screen differently. You'll never know what a particular provider is going to do and accept unless you ask her personally. There's no handbook on being a provider, so each of us follows the rules we've set up for ourselves..

I wouldn't vouch for him. I could vouch that he isn't LE. But I have no idea what kind of kinky bastard he might be behind closed doors.  I wouldn't know if he had restraining orders, arrests. How would I? I wouldn't think the ladies would take that alone. Maybe that and his personal information. I'm sure he'd be fine, but do you really know him that well? Would you let him bang your SO?

Your vouch would help with verifying he isn't LE, but I would do that on my own. Of course it's nice to know that someone thinks he's a decent guy (in general) but...

You don't know if he's too rough in the sack.
You don't know if he will attempt bbfs.
You don't know if he washes his balls thoroughly.
You don't know if he fully understands and adheres to the boundaries of P4P.

Etc etc etc....

So I saw a new client. He turned out to be a perfect gentleman and everything went smoothly during our meeting....
A few later, he texts me saying he told his friend about me and now his friend wants to see me and is that cool...
I didn't get a chance to respond until later. When I did, my new client didn't bring up his friend again but booked another session for himself.
So next time I see my client, sometime the session we get to talking and he brings up what happened with his friend. He told me that his friend was all excited after hearing about me, until he found out my price, which was more than he wanted to pay. He also apparently tries to lowball escorts. So just from that, we obviously would not have been a match!  
The friend prefers to meet with girls from BP who end up NOT  being "the girl in the pics" lol. That's how he hobbies. Whereas my new client took his time reading all about me in my website, and actually cares about getting good service lol.  
Moral of the story: 2 different men who are bffs can be totally different people, like night and day almost, when it comes to how they treat women..

Thank you for the responses.  I have been in the hobby off and on for 18 years.  I'm doing everything I can to groom him to be a good client lol. I was just hoping to get him with a more experienced provider,  who has great reviews for his 1st. I've been with many over the years that was not a fun experience and I hope to help him avoid that.  Ter is really helpful,  but it only points out that you may have to spend 1k and get 2-3 references by so so performance rated ladies that are Newby friendly to get to a better experience... At least in some cities.  But oh well,  we all went thru it!  I told him P411 was like a credit card.  He got approved,  but now he has to build a fico score lol.
