By no means a comprehensive list:
The Patroller
Takes pleasure in telling you that you’re awful. What you read, watch, write, eat… awful. Stays up-to-date on the latest jargon of whatever political or ideological movement they subscribe to. Checks to see that you’re expressing the correct opinions and tastes. Attacks you if you aren’t. (Has been known to end a Twitter thread with *mic drop* but now uses clapping emojis.)
The “Look Over There”
Keeps asking you why you aren’t talking about something else. There are always other things you could or should be talking about. If you aren’t talking about those other things, it means you don’t think they’re important, which means you’re a terrible person.
The Gnat in the Swarm
Loves a good pile-on. Joins in, just for a nibble. May not even truly know (or care) about what’s going on, but enjoys that little taste of blood.
The Downer
“Just chiming in to remind you that things are horrible and the world is ending. K thx bye.”
The Great Rationalizer
Bends over backwards to excuse or explain away anything. (Especially anything that doesn’t affect them personally.) May assume their position is objective, completely dispassionate.
The Sock Puppeteer
How many accounts can one person create for a single site? Watch them as they cheer themselves on, generate noise and confusion, and evade moderators.
The One Issue to Rule Them All
“Do you have a headache? Stop eating GMO products. About to commute through a snowstorm? Cheer yourself up by not eating GMO products. Favorite TV show got canceled? Console yourself with a non-GMO dessert.”
The Scorpion of Malice
Emerges to make venomous remarks before scuttling back into the dark… from which they’ll emerge again.
The Brooder at the Tower Window
“Ah, you fools.” (Pauses to swirl brandy in a crystal-cut goblet.) “What do you know of the world, mired as you are in your petty concerns? Alas, only I can see it all. Only I can grasp the truth.”
The One Who Dies on Hills
Won’t admit they’re wrong. Even if it’s a little throwaway fact that’s easy to check. (“Thomas Jefferson wasn’t born on that day.” “Yes he was, if you go by a different calendar.”)
The Great Decay
There’s something putrid about this person. They bring a stench of corruption to any comment thread. You could be discussing something innocuous, like recipes for blueberry muffins, and they’ll ooze in with a protruding tongue like Jabba the Hutt, and everything will feel tainted.
The Flying Monkey
Eager to attack at another person’s bidding. *claps hands excitedly*
Me, Me, Me!!!
“Does what you’re talking about affect me? What’s the point of talking about anything that isn’t relevant to me? If it’s not relevant to me, it isn’t important. In fact, I’m starting to feel excluded! Now you’ve done it, you’ve offended me…”
The One-Sided Conversation
It doesn’t matter what you say. They’ve already filled in your end of the conversation. Enjoy front row seats to their interaction with an imaginary version of you.
The Mature and Reasonable One
Makes sincere efforts to understand and evaluate another person’s point-of-view. Argues without resorting to malicious remarks. Knows when to step away to cool down.
Spam
Their new telecommuting job earns them $105.11 an hour! Isn’t that amazing?!!
