Whitepages

Is the a legitimate website to look up people for background check?I tried to look up my bil’s new wife.I paid $9.99 for Whitepage Premium background check,it started then I get page coming up that a problem repeatedly occurred and the search quits.Is it possible she had some smart computer person block it for her to keep anyone from researching her.
Perhaps I shouldn’t be so nosy but I feel bad for my bil.We went by their new house in Texas for a visit,pretty obvious she’s taking him to cleaners.He’s retired with a few million,meets this woman and they get married.Nice house,nice furniture,expensive vehicles,put in a pool with waterfall.She’s got house full of derelict looking relatives,7-8 rescue dogs,probably 20 rescue cats.It’s a chaotic atmosphere.
Teaser info on Whitepages shows she has 4 names in the past besides her present name,30 addresses,bunch relatives that share her past names.Obviously she’s bad news,
Poor guy is younger than me but he’s partially crippled due to spinal issues,hobbles around with a cane.He’s going to need his money as he gets older and I’m sure she’s going to wipe him out.
Part of my concern is that my wife will feel obligated to take him in when he’s broke.He’s nice guy,but he’s got some obnoxious traits and I don’t want him living with us.
