The question of reliability – for those who question it – in both cases has been around for at least four years if not more.
Assuming you’re not c”v thinking that there is actual vadai “issur” involved here, which most people I’ve met and question the reliability don’t go so far to say, it’s not the biggest issue in the world. The questions in your mind should be that of the organization’s standards, if the mashgichim adhere to the standards, and if the mefakchim are actually mefakeach on the mashgichim to enforce keeping in line with those standards.
By Pesach the “big” hechshers go back to basics and often don’t certify anything they don’t have to; it’s a lot of work. Chug Chasam Sofer decided to take on the task. If it’s based on certain kulas (I don’t know if that’s the case) which you do/don’t hold of, you should find out. Call the hechshers.

Did you ask the Chassidish rov what isn’t reliable and if he checked it himself?
