Petition to Rule 5 this sub

Can we please have Rule 5 as observed in r/fossilid? The jokes are out of hand with more joke comments/answers than helpful and accurate ones. Kudos to the members who are here to help. The others can create a rocksthatlooklikefood sub. I joined this sub as a gem and mineral enthusiast. I have some specimens I would like to post for identification but I feel my post would be bombarded by too many food jokes. It's annoying, unnecessary, and not what this sub is for.

Rule 5 states:

No jokes or unhelpful comments are allowed. Ever. This is a scientific subreddit aimed at serious and educational content and discussions. Jokes/unhelpful comments do not add any constructive value to the conversation.
