Caffeine at any dose gives me anxiety and restlessness. At too high of a dose (which is basically equivalent to a large cup of coffee at home or a normal Starbucks coffee) I get heart palpitations and panic spirals.
I haven't intentionally had caffeine in five years.
This is 100% a bot that's part of the former TEMU network. Every comment is weirdly cheerful, nonsensical, and multiple end in two emojis. Pregenerated Reddit username, too.
I've dealt with this particular bot problem as a mod. Noticing the pattern early on was easy because they always had posts on TEMU subreddits. Now that those subs are banned, it's harder.
Comment length. Their comments are always less than two lines long.
Tone. They always contain at least one exclamation point, and tend to have a tone that I'd say is "cheery to the point it's offputting."
Context. Reading them, a lot of the time you'll ask "did they even read what they're replying to?" The comment seems related, but directly misses the main point.
History. Look at the rest of their comments. If more than one ends in two emojis, they're definitely part of this particular bot network.
Basically every user that has comments that end with two emojis like this is a bot. Originally they existed to drive traffic to TEMU subs, but since Reddit banned those subs they've become harder to spot. I think the spammers just forgot to turn off their bot farm.
You evidently did not watch the video.
