So, I sent this message to a few of them, asking them if I knew them, and also telling them, in a brotherly sort of way, that it would have been polite if they'd sent me a message introducing themselves before sending an invite. That must have scared them I guess, for none of them replied. Now I've stopped sending those messages to random people who add me.
A lot of juniors from college, school, tuition classes (!) add me all the time. Initially I used to do a thorough background check before adding them. Then I simply started accepting all requests, too lazy to investigate. But, now, when I figure that half of my Facebook friend list is people I don't know, I reject any random request that comes. Don't care if the person thinks am rude anymore.
Most of these 'friends' are content at just adding me. And they never bother me, send me no messages, never 'like' any of my pics or status updates. So, I was pretty convinced that it's just a numbers thing... having more friends! But then there are some weirdos too. So, this chic added me on Facebook a few months back.. had a marwari name, and I thought must be some relative or junior.. and I accepted the request, without bothering to check who she was. She pinged me a few days later-
'Do I know you?'
'I don't know.. you added me two days back I guess'
'Excuse me, I don't add strangers!'
'Funny, because I don't add strangers either! :)'
Two minutes later ...'Now that we are friends, no harm in knowing each other. What do you do?'
I removed her from my friend list.
