MPA Certificate info under Miscellaneous Company section

I distinctly remember having a conversation on this site regarding where MPA certificate info should be listed on IMDb, that thread from at least 5 years ago if not longer but which I can't seem to locate. The conversation started because I noticed that increasingly someone was listing the Certificate number under Copyright, me at the time following suit in not knowing the role of the MPA then. There was a subsequent discussion on that same thread of where if anywhere on IMDb MPA certificate info should be listed. In that conversation with one staff and one contributor, neither of who I remember (although I am only guessing the former would have been @michelle and the latter would have been @marco) the consensus that the only place such information should be listed is under Certificate. Since, I have routinely deleted the certificate number from any instance of it being listed under Copyright, or deleted the MPA listed under Miscellaneous Companies. While the prevalence of it being listed under Copyright has become less and less, it has not subsided under Miscellaneous Companies. While the listing under Miscellaneous Companies does sometimes include the MPA Certificate number, more often than not the role is solely listed as "Acknowledgement" which is obviously just the MPA logo showing the Certificate number in usually the closing credits. I am just confirming again that MPA Certificate info, even listed as "Acknowledgement", should not be listed under Miscellaneous Companies. I am in a continuing battle with at least one other contributor as that contributor has routinely listed the MPA under Miscellaneous Companies for the same movies over and over.
