Apushatayid, I don’t get what’s bugging you. Nobody’s telling you to accept online suggestions and not to ask your rov.
Whether or not such discussions constitute L”H is a good question. There certainly can be toeles in the discussion; someone like you whohad no idea that there were possible issues might very well go ahead and ask their rov, but I don’t know if this justifies posting such information online.
Your grievances in this regard might best be addressed to moderation to whom it’s indeed hearsay, not to a poster who might very well have received first hand information.
