You may notice this is a spanking new registration, but I'm not a newbie or a troll.
I just want to ask, hypothetically, if you log onto a website (like, say, Mumsnet, maybe) and find something written about yourself, then perhaps it's your own fault for snooping?
Maybe if the op posts something like "AIBU to think that Joe Bloggs, who lives at 1234 Twatbag Crescent is a Prize Arse" , you may have a point.
But if the OP is posting anonymously, on an anonymous forum, and you make an effort to find out what she/he's written-- then do you still get to have a hissy fit about what you find?
Is there any excuse for searching for a person's posts and confronting them in RL about what you find? Never mind how you found out their username in the first place...
Or, does monitoring someone's online activity possibly mean you just might be a stalker?
