What kind of people do you reject/block without giving them a chance?
For me, many.
If they hit some marks or characteristic, I reject them (even as friends) without much hassle.
IRL I'm a little more flexible, but online I block on sight people of certain types.
Sadly G@G made me much more prejudiced against everyone of all political spectrums and genders and especially certain "combos".
What about you?

Also I should add people being too nice or think they have to "help" me.
I generally either block them or crap with them for a little and then run them into the ground.

Hmmm.
Except some people, I think I'll just block the whole lot of you.
