So i use p411 to screen clients. But what should I think of clients who have over 10 provider okays but they are all a year old??

A guy with year old provider oks  usually means that he's just seeing one or two providers over & over again.  I saw the same girl for 8 months without seeing anyone else, so all my P411 provider oks were over 8 months old.

My advice: book him & give him GFE++.  This guy is (probably) a big repeat customer.  Make him forget about those other providers, and you will reap the benefits.  Good luck.  --z

If it makes you more comfortable contact a few of the ladies listed on the provider okay make sure the gentleman is okay if you are nervous about the date of the okays,but I would also look at when the gentleman's account started.Could be just like the other person said maybe he's been seeing the same girls and decided to try something new.

They will slobber all over you and you'll need to change their diapers.

Tell them to come back when they've graduated from college and have jobs.

Well, I tend to rotate a few Favs. Occasionally, I'll meet a new lady if I consider her a prospect.  (I'm not interested in seeing how may times I can notch my 6 guns...  I find the sex better on return engagements.)
There are lots of reasons a client might not see new ladies, just as providers might go stretches without reviews.
Complete your screening & see the guy.

ok thanks for all the advice. I just prefer to see guys with recent references. If the girl hasnt seen him in a year, more than likely she wont really remember him sooo.... just making sure it didnt mean anything bad!

Yes, she may usually not remember but for P411 and Date Check they have an actual website of info that they can go back and refer to to help them remember.  

I haven't ran into an instance where a lady had given them an ok on either site and didn't remember them regardless of how old the OK was.  

Check with the ladies before you dismiss the gent.  
Thanks
