Joseph, I can’t see anything. I rely on gedolim. I just don’t rely on kol korehs without further guidance from my own rabbeim. Forged signatures on kol korehs have been known to happen. Furthermore, as Rabbi Fuerst (who has more emunas chachamim then you or me) said when I asked him to clarify his comment about Rav Eliashiv, “she’eilas chacham chatzi teshuva”. Kol korehs aren’t written by gedolim. They are written by askanim. BIG difference. As such, they aren’t always Torah MiSinai.
The recent Yated article about askanim highlighted the dangers of askanim with no daas torah running the agenda. If you speak to any rebbe you are close to, I’m sure he’ll have plenty of stories of askanim and the damage they cause. I’m not saying ignore kol korehs either. I’m saying to speak to your rav or rebbe for more guidance. Nosson Kaminetzky said that when he spoke to Rav Eliashiv about the lanaguage of the kol koreh against his book, Rav Eliashiv said that he never put it in such harsh terms. My rabbeim tell me to find out further guidance about every kol koreh that comes out. If your rabbeim tell you to follow them blindly no matter what, then kol hakavod. My mesorah is different.
