May I suggest Krixwell watches any further Worm YouTube content on incognito mode?

I don’t think the problem arises from what I watch in this case. I don’t watch on YouTube itself, but rather through this site, Polsy, which embeds the videos without showing any related video thumbnails or titles (it’s a very valuable tool for livebloggers and their ask screeners). I don’t think anything I watch through that counts towards the algorithms, though I’m not 100% sure.

For instance, I watched this Homestuck video several times while setting up the recording, but haven’t seen any impact of this on my recommendations – though if YouTube did count that, it might’ve only counted that as one view since I don’t think I reloaded the page, whereas watching Worm Abridged Arc 1 and 2 once each was starting a series.

If it turns out I’m wrong and watching embedded videos does count, then it might help to switch to this other site, nospoiler.com, which does the same thing as Polsy but uses Flash instead of plain embedding. Or, yes, incognito mode might help.

But yeah, what I believe happened is that the algorithms noticed that I uploaded a video titled “[REACTION] Worm Abridged | Act 1 and 2” (whoops, that’s supposed to be “Arc”) and figured that I’d be interested in a video titled “Parahumans Worm Abridged Arc 3”. As such, my first step to avoiding this will be creating a channel on a separate YouTube account to upload Worm videos (and other reaction videos I might do) to, so that I won’t see whatever impact they have on recommendations, because I’ll be using my original account for those. I’m going to delete the video I already did and re-upload it there, too, though I’m not sure that will remove Worm Abridged Arc 3 from my recommendations.
