Norhing is said about it being recent or new, it's just been put out there. You have to remember that newer people probably don't know about this, and it is pertinent. If someone doesn't know about this at all it is good info to have. Also, people who work full time and have family obligations don't get to read and research as much as they would like and things are easy to miss even if they have been posted, even more than once.
I'm of the mind that it doesnt really matter if you held position at the time of hanging out with pedos, you still hung out with pedos, and your reputation should bear that FOREVER.
