From now on a new rule is in place
Rule 8: The subject of a post must be highly visible, which means that it is either highly upvoted/liked/viewed, posted by a public figure or widely known of in society.
Reworded rule:
Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this.
c/the_dunk_tank should be about dunking on capitalist/reactionary ideas floating in society not about finding one idiot to get mad at, so the rule has been introduced to make sure that is the case
What's the bar for "well/widely known" here, would dunking on some loser like Stefan Molyneux or Ian Miles Cheong be allowed? They are pretty damn irrelevant compared to the
/ 
realm where they have actual reach.
The purpose of the rule is to stop dunking on one(1) upvote comments, these are public figures even if relatively obscure so they would be allowed
