Personal information that you furnished yourself in this forum is not private. Why would you object to someone posting what you had published in public in the first place?
They are not talking about the information they furnished.
You've been here 5 weeks.
They're talking about having decades-long conversations (I've been here 20+ years, Hay Dude 10 years, ovrszd 16 years, for example) between possibly hundreds of other TBN members that have been here just as long. In those thousands of conversations, you occasionally mention, for example, the town you live in, the school you went to, the name of your spouse or child, the sex of your spouse or child, where they went to school, what you do for a living, etc...
Then you get someone that for whatever reason, decides they have an axe to grind. They start by taking shots at each other on the discussions. Then it turns into seeing which one can take the most, meanest, most demeaning shots. They never let it go, and they just keep taking shots at each other, over and over again. Then they start posting personal information that they've either gleaned from years of conversation, or, super creepy, going and looking up the other person's personal info based on years of comment. Then they post that.
So we're not talking about things we've talked about over the years. We're talking about people taking those things and turning them into threats and insults. That crosses a line that shouldn't be allowed.
