> Because if there's one place where Google didn't solve spam, it's on YT's comments

I do believe that this problem is very self-inflicted (and perhaps even desired) by YouTube:

- The way the comments on YouTube are structured and ordered makes it very hard to make deep discussions on YouTube

- I think there is also a limit on the comment length on YouTube, which again makes it hard to write longer, sophisticated arguments.

- Videos for which a lot of comments a generated tend to become promoted by YouTube's algorithm. Thus YouTubers encourage viewers to write lots of comments (thus also a lot of low-quality comments), i.e. YouTube incentivizes that videos are "spammed" with comments. The correct solution would be to incentivize few, but high-quality comments (i.e. de-incentivize comments that contribute nothing valuable (i.e. worth your time to read)). This makes it much easier to detect and remove the (real) spam among them.
