It's all a matter of being smart enough to know what to look for. Very easy to verify who someone is and that they are legit.
If you are simply looking to verify that the name that a gent gave is indeed on Facebook or LinkedIn then no, obviously that isn't screening. If you are digging deeper then that and making connections that would be quite difficult for someone to "fake" then it's a rather fool-proof method.
So it does work for SOME providers in SOME circumstances.
It also works for SOME gents who desire to be screened.
A lot of "hobbyists" here on TER are very quick to offer up the advice of "NEVER EVER EVER GIVE HER YOUR NAME" and go on to recommend P411, Date-Check, provider references, etc, etc. The sheer fact of the matter is that not every woman will accept 3rd party verifications. Many women in this industry will only see you if you provide verifiable "real-life" information. It doesn't mean that that woman is "up to something" which is so commonly the message that can be inferred from reading a lot of newbie threads. What about the newbie gent who wants to see one of the ladies that require personal information? Should they just mark her off of the list because the feedback they get here tells them to NEVER EVER provide that information?
.The only tried and true advice for both clients, prospective clients and providers in this industry is to do what makes you feel comfortable.
Hobbyists: if you want to see a woman then do what she tells you to do for screening. If she is well reviewed or has a good reputation and has been around for a while then there is no reason for you to feel any less safe giving her your information and going to visit with her then you should feel when you don't give a provider your real information and go to visit with her.
Providers: as far as screening goes, it's my opinion that everyone should screen in the fashion that makes them comfortable. If 3rd party sites like TER, DC, P411 etc make you feel comfortable then by all means use that. If having someones full name, employment, etc. makes you feel most comfortable then do that.
If law enforcement wants to meet me, you or any of us then they will. And no amount of screening is going to protect you from that. It is well documented that law enforcement have used fake LinkedIn accounts and Facebook accounts in effort to be screened. It is well documented that law enforcement have infiltrated DC, P411 and TER in efforts to be screened. It is well documented that law enforcement have obtained employer references from legitimate national companies in an effort to be screened.
Bottom line is to do what makes you feel comfortable but don't discredit what others do and what works for them because it isn't what you would do!
