Q: can mobbers be bots too?

[Former-GM-Circe]

Skill of bots depend entirely on the skill of the botter, in both coding the bot, and actual gameplay to recognise what an efficient bot would do.

If in doubt, report.

There's no punishment in reporting someone who isn't a bot. If you report, we check, and if they are, they get banned. If they're not, nothing happens and there is no harm done.
