There's a 0% chance he's blacklisted from google by name. Google doesn't do "hellbans", they just delete your fucking channel (or just adsense) if they want to. He is, however, horrendous at social media - YouTube in particular. Let's really break it down.
YouTube's current "meta" is engagement. They want consistent, deliverable, and engageable content. What does that mean, exactly, and where is Rich fucking up?
Quality - YouTube wants a higher grade of "professional" (marketable) content creators and in a perfect world these would be comparable to TV personalities. They want more Markipliers, Jacksepticeyes, whatever. Content Creators have free reign to be a little risque - but never outright offensive - either by themselves or in the games they play. They will prioritize content creators that put a bit of effort into videos (either through editing, lighting, calls to action).
Rich - Literally runs 45 minutes of pre-stream for a 3 hour stream and then plays literal hentai/fetish games and horrible games "ironically". Uploads old movies and other nonsensical garbage as well.
Community - YouTube wants people to create communities that engage in metrics (hence the "like, comment, subscribe" spiel in every video ever created) and knows what a "healthy" channel looks like. It's largely preferred if content creators can consistently turn subscribed users into viewers. They prefer content creators that brand themselves (which is why you see every YouTube thumbnail include the content creators face).
Rich - Has 34,000 subscribers but can't break 1k views on many videos. Rarely anyone comments or chats in his videos/streams. His old community largely hates him. Will go 45+ minutes without showing his face and makes "ironic" bad thumbnails. Still uploads SA animations despite the bad blood between SA and him - as well as the bad blood between everyone and Shmorky.
Consistency - One of the "keys" to YouTube is consistency - a consistent upload schedule and consistent content. If it's daily or weekly, just as long as it's consistent it gets a huge push by YouTube. The content should be consistent as well - this is why you see larger content creators typically have different channels (a Let's play channel, an animation channel, a twitch VOD channel, a personal vlog channel). A good YouTuber will go so far as to have some kind of posted schedule so you know when to "tune in".
Rich - Has 0 consistency. Sometimes will upload 15 times in a single day, sometimes will go months between uploads. Will post bad LPs, political stuff, old movies, old Chinese movies, and hearthstone pack openings. None of these things are even partially consistent. Has no posted schedule and whenever he sets a loose commitment (ex - "I'm going live on Tuesday 5PM") he always is either late or absent entirely.
Discoverability - YouTube has a deep network of algorithms that probe keywords and tags to try and get your content in front of people who might be interested in it - something similar to the website's own version of SEO. Even really shitty content creators are able to skate by with clever SEO (most notably DarkSydePhil).
Rich - Uses no tags or keywords. Rarely even uses descriptive titles.
Content - YouTube is incredibly afraid about "controversial" content - politics, extreme ideas, and so on. It's known to demonetize/unprioritize what it considers videos and channels promoting "controversial" ideas to a point where even "news" channels try and cover those topics in incredibly specific ways. It wants clean and sanitized content.
Rich - Uploads a video called Great Moments in Chinese Cinema: Children Suicide Bombers and Zombie Hitler.
Rich is almost certainly on a list at Google - but not because it's a block list or anything - but because his channel seems like a channel that a robot operates. A robot that buys subscribers or a robot that bought the channel from someone else.
