Feif un, I hope you’re just misinformed, and not deliberately twisting the well known facts, this major scandal in Monsey that rocked the whole world had a hashgacha of a ashkenazi “yekke” rav, running a congregation of “clean shaven” members, he is as far from chassidish as you are..
It’s very simple, the chassidish hasgachos (as I said before, this includes yeshivish frum hashgachos as well) have different standards, starting with cholov akkum (not going in debates whether one can be “maikel” on it or not, it’s definitely a compromise in kashrus by all means), bishul akkum, hefsed meruba’s with the large companies, way and system of koshering, bedieved’s, and the list goes on.
p.s. again, the term chassidish doesn’t automatically make a hashgacha reliable, some of the private so called chassidish hashgachos are worth no more than a full air balloon, but the strict and reliable ones are of way way higher standards than the national ones..
