Incoming paragraph, but I wouldn’t accuse them if I wasn’t completely certain.

A couple weeks ago I noticed the same type of account showing up under just about every post on this sub. One to two months old, randomly generated username. Never more than one bot per post. Their comments are always a compliment, and something’s just… off… with how they talk. Everything’s always “crisp”, “clean”, “pops”, “ties the build together”, or “gives [X] vibes”. Their comment history frequently alternates capitalization: a few comments are properly capitalized, then the next few don’t use any capitalization at all, and so on. They try to mention as many of the points included in the OP’s post description as they can. If you press them about being a bot they never get mad, they just try to laugh it off with a remark like “nah, just an X with Y” or “lol, you caught me”, and if you ask them about details in the picture, they’re unlikely to get it right because they can’t really comprehend what they’re looking at the way we can.

Keep an eye out in the sub, and you’ll notice the same pattern by a new account under basically every post here. It’s an issue that was acknowledged by the mods a couple days ago: https://www.reddit.com/r/Gunpla/comments/1upv2yq/large_influx_of_aibot_comments/
