Jim you imbecile that's the AI Overview
O algo is a racist dogwhistle that originated from Soyjak Party. The character portrayed as the o algo guy is literally a racist hispanic charicature. The goal of the "O algo" community is to desensitize people to real world issues.
The reason the AI Overview is unreliable is because it can't F**KING TELL what's a dogwhistle or not. That's why racists or pedos never get banned because they all use dogwhistles to convey information, and the AI moderation that tiktok (or pretty much any other large social media app) uses never detects it.
Not only this, but dog whistles aren't meant to be blatantly obvious. That's the ENTIRE point.
