I’m not on Reddit, but I found the Reddit Content Policy:
https://www.redditinc.com/policies/content-policy
I don’t see the above policy mentioned there.
On second thought - just trying to understand what happened because such a policy is so ridiculous.
Reddit mentions “communities.” Do users set up their own “communities” on Reddit? If so, do those users establish their own rules for their communities? Maybe a Reddit community established that policy for its own group.
Otherwise, it must be a joke post.
