So basically we have an "anonymous" posting on the internet from somebody who heard from some unnamed posek that the gittin are possul.
If that's not hearsay I'd like to hear what is.
Someone quoting the anonymous posting?
I find it hard to believe that a reliable, responsible rav would be motzie laz just to answer a talmid or a random person asking a question with no toeles. Even if its true, I fail to see the toeles, not to mention Lashon Hara. I don't want to judge a rabbi, especially since I don't know who, but the gemara states clearly that kol mi shaino yodeah tuv tav bgittin vkedushin lo yehe esek imohem. Is this rabbi a tuv tav? (No getting invited to do a sidur kedushin, unfortunately, doesn't count these days)
If he is, I would ask him:
Why did he only decide it was appropriate to speak up now after its national news?
Why be marbeh mamzerim, and aishes ish biyisroel when we can just be mevatel the first marriages before voiding a get issued by a respected beis din?
Is he active in helping those who received these gittin to get "proper" gittin? Shouldn't that be priority number one before being motzie laz to anyone who asks?
