why the hell didn't anybody google anybody?

The show ran background checks on the girls but the guys and their moms met the girls on the show and they live in the house with them. There is no computer access or phone to do background checks themselves.



There is always too much month and not enough money.

There had to be some contract clause that prohibited any outside research, as that would have ruined the various reveals. Also, they probably had some rule against using last names, so the contestants wouldn't have been able to Google each other even if they had the opportunity. (This would have been taped before any of the network promotion, before the last names were public.)
