Well as most said, dunno know about everyone, but there are tonsss whom u CAN trust.
When u start chatting to some ppl everyday and discussing the show at first, then ur likes and all, the trust would come by itself!!
And I'm usually very comfy with all the old and active member....cz I dun think any stalker wud be soo active and wud many soo many post just to stalk someone LOLZ.
So ya don't be scared. I have IF friends, whom I trust fully, they are on my MSN, FB and they know where I live, know all my activities. So ya...just enjoy, discuss the show, u'll make trustworthy friends urself 😊
