Sentinelese

The Sentinelese is the tribe of North Sentinel Island. They are the last hunter-gatherer tribe in history and will lash out and attack outsiders. Basically, you shouldn't mess with them.

Jessica: Hey, have you heard about the Sentinelese? I've heard they're the last hunter-gatherer tribe in history!
Brandon: Yes, they live in North Sentinel Island and will lash out and attack outsiders. You shouldn't mess with the Sentinelese, Jessica.

Bot Sentinel

A website that tracks bot accounts on Twitter. While useless for invalidating arguments, it can be a useful reference to determine if a Twitter account is arguing in bad faith.

I checked Bot Sentinel and it said there was an 88% chance you're a trollbot. I'm not saying you're a bot, but maybe ease up on all the propaganda and it'll be easier to discern you from one.
