i get some twitter updates sent to my phone,so i got one from demi lovato and later on when i went on her twitter on the internet, there were many more than the one i got sent to my phone?

My facebook is deactivated but I seem to still get emails about people adding me and things why?

I deleted/removed someone from my friend’s list and then received a confrontational message in my inbox… is that the way Facebook works or are they doing something funky? Thanks for your help.

I had a friend on facebook, the next day i didn’t. I looked on all my friends list and searched there name and there not there. But when my friends are on there account that person is still there.

I just joined twitter a few days ago. I posted a few messages (tweets?), nothing fancy. And yet i have people following me like herds – about 10 an hour. Does that make sense? How did all of them find me? What’s in it for them?

I heard that youtube and facebook dont work in china. but i have this friend in taiwan that uses facebook and youtube o.o. so does that mean, facebook nad utube only works in taiwan?
