Although she has "exposed" the affair, I would just urge you to contact a DB coach before you seek out OM's fb friends in an effort to shame him.
IMO if shame were effective, it would have happened by now. Public shaming tends to make the affair partners cling to each other more, to prove that their love is the "real" one and it's them against the world. A LOT of people want to be "Right" so if anyone challenges that and says "you are doing wrong" they may want to be right so much, that they marry.
And imo, despite Georgia's very articulate reasoning, I have to respectfully disagree. I think it makes you look vindictive, and or in the fray rather than being above the fray of the A.
IF she has told everyone about the new r but is in the same house and you come across as being indifferent b/c you are all about your son and setting an example for HIMl then the OM is beneath you, beneath your even mentioning. That doesn't mean you don't tell HER about boundaries...
Outside of that, I probably wouldn't even acknowledge him;. But again -- seek out at least one session with a DB coach before you enter the public discussion.
BTW I actually have seen a LBw publish a message on my high school class fb page. She exposed the affair her h was having with a classmate. She warned my class about OW, who was also a classmate.
As the admin of the page, I was asked by FOUR other people to "please delete" the message she had left. They felt it was "very inappropriate" and or "pathetic" for her to try and punish him by telling all his high school friends.
I felt pity for her. I really did, b/c I know the LBw was in pain and felt the urge to "do something!" about the affair her h was having.
But man, that fb message was NOT well received. Everyone looked at the betrayed spouse like she was unstable and desperate. Was that fair? God, no. But it's how it went.
And the affair skyrocketed and the partners are still together.
So the only time I"ve seen it done, it did not help and in fact, it sure backfired. In fact, I hate to tell you this but one classmate said something to the effect of "no wonder h had an A, his wife is a b1tch." Ouch.
See what a DB coach says...I'd defer to their advice
b/c fwiw, I can tell you that the DB coach advice I got, never hurt my situation.
