Many channels I saw were inspired by SpiffingBrit's claims.

He claimed that creators using the Community tab was disproportionately rewarded by the recommendation algorithm. (Since the community tab was a new feature, YouTube wanted the feature to show up in peoples' feeds; but since few creators were using the community tab, it meant those that did got a big boost). -- IIRC, this evened out once everyone started using the feature.

SpiffingBrit also suggested that copy-pasting many of the trending keywords in comments would help the recommendation algorithm show the video. -- This turned out to be incorrect; but for about a week, most of the comments I saw in a bunch of videos had the same 300 words copied and pasted.
