I don't think it will be useful, there's no way to tell if an unofficial derivative has the same setup/versions/packages as an official Ubuntu release, it will just lead to confusion.
Those questions should just go on the Unix and Linux StackexchangeStack Exchange. There's no need to leave disparaging comments or downvoting the person for posting the wrong thing, just flag it for migration it and put "This should be on unix/linux se" in the text field so a moderator knows it needs to be moved.
- For bonus points be neighborly and upvote if appropriate on UL and flag comments that will then be out of context.
Sort of the same reason you wouldn't post about an unofficial derivative on an ubuntu list, or ask for ubuntu support on ask.debian.net, etc.
