This is a tricky problem even to define, because there's "Reddit" which is the owners and paid moderators, then there is "reddit" which is the universe of its subreddits and its unpaid, unaccountable moderators.

For example, it's been well known for awhile that if you subscribe to any of the men's rights subs, you are auto-banned from several of the feminism ones (including TwoXChromosomes). That kind of thing certainly isn't lenient but also isn't under Reddit's control.
