Can you have a ten minute phone conversation with someone and pick up where they are coming from?

If so, that's what you should be doing with guys without references.

If during the call you pick up bad vibes, tell the caller you have to go and put them on do not see.

Remember, your safety is paramount.  Never forget that.

You can also suggest to them that they join a screening agency like Room Service 2000 or the other ones.

then ask them for a license or other personal info.  Newbies will be reluctant to give this info but you need it to feel secure.  If they're not willin', they're not playin'.

screen, screen.  Your safety comes first.

I did have a lady in LV ask to see my plane ticket to prove I wasn't from there.  But, I assume LE can get fake boarding passes as well as fake ID's.

1) Make them join a verification service. Get real full name and check blacklist and sexual predictor list sites. Not what I would do but works.

2) Get there real full name, real age and a traceable phone number (not a hobby phone) and run a back ground check with that also checks for known employers. Also check the blacklist sites. Call him on that phone. Check ID at the door.I know a lady here in Utah that has had great luck with that method.

3) Get there real full name and employment information. Call and check to make sure he really works there using a made up story and ether talk to him at work or make him show you ID. Check the blacklist and sexual predator lists as well.

There is likely other was to do it that I don't know about. I would also suggest talking on the phone a bit to get a feel for him and always trust your spider senses with any of the above. There is now perfect screening method not even the reference system but the above should weed out many of the bad clients.

I don't think I need to say this to you as it seems you are already screening your clients but every one needs to screen everyone in this hobby.
