Old computer saying but holds true in all situations.
The internet is nothing but a way for lazy people to scam people. And so called background checks are usally a waste.

Unless you have access to a private investigator in a birck and moter store, you are dealing with the same crap you have with online dating. you have to trust a web page that you are getting accurate infor.
And as one poster said-dating is bad enough without background checks until you are ready to move in or get maried.
Use your instincts-cheaper
