That is the problem. There is no way that the forum could verify every scam accusation, nor should it have to now that there are more appropriate services available for this. Since we can't make exceptions to allow for people to post the personal information of scammers, we have two choices:
1) Remove all posted personal information, like Reddit.
2) Allow everyone to post personal information about anybody.
Bitcoin attracts a lot of scammers, so I would tend to err on safer side of allowing all personal information. Not to mention, if it wasn't posted here, it would just be posted somewhere else. Public information cannot be made unpublic.
Right.
I do feel for innocent victims of doxxing, though. I welcome suggestions on how to improve forum policy in this area. However, forum policy must be consistent, and I'm not going to start deciding who's guilty and who's not (again).
I've been thinking that maybe it would be an improvement to require that dox be posted along with sources for all of the data, and ban dox that doesn't come from a "public source" (government site, news story, Facebook, etc.). This would make casual doxxing more difficult, help readers determine whether the dox is actually accurate, and hamper distribution of info obtained from illegal sources (hacking, etc.). I'm not sure that it would help enough to be worth the trouble, though.
