Many TikTok users are signing up for RedNote, an actual Chinese social media app. US users consider this a better option than American offerings such as Instagram, Twitter, or YouTube.

Where do you think that US users heard about Rednote? If you are not a TikTok user, then you would had never heard of this app. Clearly, TikTok used their algo to "raid" Rednote, like a Twitch stream raid.
