I do find that there is no better indicator about the quality of a sub-reddit, than that class of requirements.
The more karma/age/posts they require, the more likely the place is a cesspool of some sort.

The whole idea is utterly stupid because it is far too easy to get on popular low effort subreddit and get some points for posting absolute garbage, then go and bother people in niche subreddit.
If you have to wait 2-3 days to comment the moment as they say has passed and very few would read it.
