My Rav (who has 6 daughters) does it. he just leaves the table while they do. He has semicha from Chofetz Chaim.
The roshei yeshiva to do not support this. Perhaps his daughters do this, and he doesn’t think it is worth fighting them over.
Besides, I am sure that chofetz chaim has given smicha to some nutcases. They’ve been around for 75 years, and sometimes that just happens.
