What are [BOT] users?

[maelcum]

Hello.

Sometimes I can see usernames with "[Bot]" at the end. Are those users that have been identified as bots by their behavior? Or actual bots programmed by this sites' admin[s]? Or something else entirely?

I've attached a screenshot, if it helps.

Thanks!

Hi, not sure if that's just a bot that scrapes public data or if that was an installed bot
