that's stretching it to call that a threat.
There is absolutely ZERO reason to publicly post "I know his real name and where he works" about an opponent in the middle of an Internet discussion unless one's intent is to make an implied offline threat in order to intimidate the opponent into shutting up or conceding.

IMHO, ANY poster who makes such an implied threat as you have described above, should be immediately banned from FR. To suddenly raise the subject of "who" a FReeper is (real name) and "where" they work (place of employment) serves no purpose except to threaten and intimidate, and has no place in any civil discussion.

There was no reason to post this other than to intimidate the victim.
