Another demonetization datapoint

Perhaps posts about limited monetization are reaching saturation, but it just happened to me for the first time, so I'm contributing my experience as yet another datapoint.

On one of my channels that has over 200 videos, one solitary video entered the new "limited or no ads" state. I got no notification of any kind about it, I just happened to notice it in Video Manager. I have no idea why that video was picked, as it is similar to many others. It was part of a series of videos about disassembly of a construction tower crane. Not sure why that wouldn't be fully advertiser friendly. It had nothing controversial in it that I know of. None of the other videos in the same series were hit.

Anyway, I requested a "manual review", and about 3 hours later I noticed that it was back to being fully monetized (again with no notification). Which was faster than I expected.

My only real complaint about the process is that there appears to be no notification sent about any of the actions that happen.

Of course, I could spend a lot of time speculating about why that particular video. The only thing I could think of was that there was some construction terminology used that was misinterpreted as sexual innuendo or something weird like that. The title of the video is "Tower crane disassembly Day 1 of 4: Removal of top segment". Maybe "removal of top" was considered something sexual by the bot, LOL, about the only thing I could come up with.

Edit: Fixed wording to clarify that this is the new state of "limited" ads, as opposed to the old state of "not advertiser friendly thus no ads".

Edit2: Half a day later, I received an email notification: "Great news! After manually reviewing your video, we’ve determined that it is suitable for all advertisers". So, I got a notification half a day later about the results of the review, although I never got a notification about the problem in the first place.
