Why don’t you just put a comment into your records (after all you can batch add it at time of upload) asking it not be touched, rather than telling people universally they should not add an ID until 1 month or whatever.
Yours is very likely the minority use of this process, far more often it is new users etc, and going a month or longer to either see an ID, or get a comment to try and add something is likely to be demotivating to remain on the platform.
