Is it important to have D ate Check?
if they are TER whilelisted, that's good too. I also heard of LUX Verify.  
Which is the best way to go?
Thanks!

A provider told me as a client that P411 was the best for a person to join.    You check their ok's , reviews given by TER,  whitelists.     Pretty good check.     The provider that told me was actually a member of Date Check too.   See their driver's license and they are identified as a member in P411 .

Of the 3 I feel most confident with P411...TER whitelist is good as well...I'm on DateCheck but haven't really had the need for it...

It's just that I hardly see whitelist ok here on TER. P411 is my favorite. It's frustrating when they don't have any okays.

Very subtle indeed...3 yrs worth of reviews and you are just now asking about verification? Nahhhh I ain't biting.

P411 took my profile down cuz sex workers and websites was crying about me talking promoting prostitution on all websites is illegal...I lost my ok on website.Discriminating analyzing.Discriminating business.Sex workers discriminate on each others.

Her p411 profile says "newbie friendly".mabe she first started off not screening any clients and then ran into a few not so good clients that make her want to screen them now.it happens

I couldn't log in to p411 for a while there.

P411, DC, and RS2K, plus TER whitelist referrals should be enough to satisfy just about everyone.  Not familiar with LUX verify.  For me, I think P411 is the top of the list, while DC is the least expensive to join for a lifetime membership.

I think P411 is fantastic for providers screening clients.  You can also reach out to a few reputable ladies who will help you out as well.  Best of Luck.
