if a girll you liked told you shes been with 30 people would you judge her for it and stop liking her?

Depends on her personality.

Not sure how you can just stop "liking" someone at the drop of a hat. We are either attracted to someone or we are not. And when we are? We can't turn that off like a light switch. There is no switch for that

And some girls give out way too much information -- it doesn't matter how many people i've had sex with, it's none of my boyfriend's business, and it's not up for discussion. Hasn't been since we have been together for the past six years, and he's never asked. Why? Because, again it's none of his business and he's a gentleman, not anAsshole. I couldn't care less about his sexual past, either. That was then, this is NOW. Right now, we are together.

Been with and sleeping with are two totally different things. If she said she was with 30 people there's a good chance she's quite popular and has a lot of friends. That wouldn't stop me from liking her.

Yeah
