I have no idea which TRA frequently travels and might be engaging in illegal activities since, quite frankly, that description doesn't narrow it down. In cases where there are receipts of criminal / abusive behaviour, then I have no sympathy for the comments that follow. And there are quite a lot of receipts which, when some utter random called themselves "Julie's Ghost" after my wife and began posting fiction about domestic abuse, were lacking.
I'm not unsympathetic to stalking, but see little evidence of it on KF. Things like criminal records that don't involve others are exactly the sorts of things we should know about. Things like my wife's Grant of Probate which a man bought, or otherwise accessed, are less interesting and do constitute stalking. Had I, like say Yaniv, a criminal past, then I might just have to accept that there will be discussion of it.
Some, I think, complain that they are "victims" of KF whilst abusing - in pretty extreme ways - their perceived enemies. Using someone's dead wife's name to post lies is not remotely sane.
In short, some have it coming, can object all they like, but we're still going to discuss - and laugh - at them.
