The sub in question has had polls and surveys posted to it, popular ones which have remained on the front page of it, and they've received paltry engagement (~10,000 engagements).
You're making it out as though that one entity has corrupted the site, which is a plainly hysterical claim based on the evidence.
>Folks from there will re-post links (or share via chat) to "controversial" posts in other sub-reddits to coordinate brigading, for example.
Do you have any evidence for this? Because discord groups to disrupt Reddit aren't unique to T_D and the hyper-leftist ones far outnumber those on the right, as with their meta-subreddit parents.
It's disappointing to see Reddit drama appearing on this site as often as it is. I remember a time when HN wasn't really on the Redditor's radar. What good times they were.
