I don’t know exactly what it is but I’m sure that’s it

Sure, it’s either of an investment scam, a tech supoort scam, a side job scam, or a subspecies of those. I can recognize it at a glance, because, statistically speaking, they make up 70% of Japanese ads in my YouTube feed, as of November 2025. Google really wants me to get scammed for some unknown reasons.

“優良株” on the left is the uploader’s YouTube channel.
”節約看護師りょう” on the right is the victim YouTuber of the identity theft.

Apparantly, the advertiser’s “節約看護師りょう” in the tagline is a name of YouTuber “@ryonurse” who has nothing to do with this illegal activity but is just a victim of the identity theft.
And, look, ”優良株 (Blue chip stock)” is the name of the guy, @GoodeCalan-n3n’s YT channel where the ad video is uploaded. While it’s never mentioned anything about stock, or even simply about invenstment in the video or in the description, pretending an innocent content created by @ryonurse. On the other hand, it’s weird to see the same guy shows its true color by the blatant, aggressive channel name like this.
But anyway, the guy’s goal is just to connect with the unsuspecting eldery’s LINE account—more private, more closed envionment. This has already been a widly-known scheme.
