There is every incentive to post false information alongside a dox, or to post non public information and claim its a dox. Watch this:
"This scammer SaltySpitoon, sold me a bitcoin miner 6 months ago and now I don't want it. He is a scammer and he shot my chicken in the face. I want my money back or I will post his information". And then that gets indexed by search engines. If you pay me, I get money. If you don't then I post your dox alongside my false information and your real name (Ytlas Nootips) is forever tainted even when you conclusively prove I just made that up and you don't even have a chicken.
But again if someone did the above with an alt account to a staff member they'd be banned and the thread deleted. You know that's exactly what would happen, we can even run the experiment if there are any admin volunteers.
No one moderates false claims, it again is up to individuals to clear there own names. So in the case above, you post your counterstory, if I'm falsely claiming that I should get my money back, I lose my credibility. Your argument could be said about scam accusations and all other things. It is the cost of doing business pseudononymously. It comes back down to what recourse people have. Hurting people's means of personal investigation means there is no recourse for anyone.
You can clear your own name
on here, I'd lose my credibility
on here, but no one coming from off site is going to read through 20 pages of abuse from a cloud of shills to work out who was right. Especially when trust ratings aren't shown to non logged in users so even the crazies seem moderately not crazy.
You would be permanently damaged and you're saying there is no way for anyone to fix it. I mean, now we're talking lawyers to get such a simple thing fixed.
*edit* just like the person who was just banned for having their message deleted 3+ times and they kept reposting it. It has less to do with the content, and more to do with the spam.
You claim that his dox are posted on bitcointalk? Link?
Yeah, lets see if admin accounts can get auto banned :/
