You linked to an HN thread which linked to a reddit thread as proof of this. I would like you to know that is absurd since the reddit thread makes an accusation with no proof.
The 'proof' is a screenshot of a post that was called '92 of the top 100 subbreddits controlled by the same 5 people' that got removed. Why did it get removed? Who knows?
Do better. If you want to be better than reddit don't do the same dumb shit that it does and check your sources.
