Sometimes, answering your questions takes a little detective work. I know that love and relationships are complicated, and you have only so much space in order to express yourself.
Just forgive me if I make assumptions, okay?
My first assumption is this: he's randomly sending "love" e-mails to 100 random chicks on a dating site or (gag) Myspace. Right? Surely he's not running around a club telling everyone he loves them. He's just cold calling every girl on the Internet he can find and being all "Sup. I love you. Hit me back." And then 50 do, and he continues to work his lame magic.
Am I close to right?
What a pathetic human being. He's not being sly. He's a douche preying on stupid people on the Internet who really want to believe that someone they have never met can love them.
To answer your question: you avoid guys like this by never, ever believing anything anyone says over the intertubes who you have never met.
Why do you think it's on the internet? If he has five one night stands a week, he could easily wake up the next day and try to convince them that he loves them. Do that for twenty weeks and you've got your hundred. Plus, if he's good at it, he might be very convincing. Also, it might not be one night stands, it might just be a date or two, but if you date five nights a week then within a year you'd have a couple of hundred.
Obviously no-one's going to respond to the kind of email you wrote. If he's getting 50 women out of 100, I'd like to think we're a bit smarter than responding to some rubbish like that.
if he could get that much sex he wouldnt need to tell anyone anything
I think the phrase "out of that maybe 50 will respond back to him" infers some sort of call or email. If they were face-to-face, it would probably be described differently. From the information in the question, it really does seem like the women involved are rather gullible and possibly desperate.
Real love isn't instant or even something that can really happen quickly. It takes time to truly care deeply about someone, so you shouldn't believe a guy who says he loves you really early into dating or a relationship. He might be trying to just get into your pants or he might really like you and be infatuated, but love takes time and people should be more careful with that word.
"Sup. I love you. Hit me back." hahaha
I'm thinking text messages...
i know alot of women that get in trouble this way.
love is a serious thing!
