I filter like whoa, and make no secret of it. I have a fic filter, a people-I've-met-in-RL filter, an old-EQ-friends filter, and so on. I do try to look at the whole unfiltered megilla now and then, but there's just no way I can keep up with it all on a regular basis.

I've never locked a post. Frankly, if something is THAT personal, I'm not going to be posting it on the internet to begin with.
