The bot is 1m old. Just wait until it gets suspended for "multiple, repeated violations of the content policy" (translation: "don't you dare to shoo the botters! Bot = activity!").
This account exhibits multiple major traits commonly found in karma farming bots. It is extremely likely that u/Yagirlbella_ is a bot made to farm karma, and it is recommended that you downvote their posts to hinder their success.
That's probably the banworthy part, arguably amounts to "brigading."
Oh sure, I mean, I couldn't care less what Reddit The Company decides to do with Reddit The Website, or what Reddit The Actual Human Userbase thinks about it. Fuck em all.
But I can also see that bringing consequences on to a bot that calls for mass downvoting of individual accounts could be justified, with disregard to what platform the bot operates on.
