It would be a coalition.

One person would have control of the account though, because it'd be unwise to trust everyone in the coalition with the account's voting power.

Multiple people would donate their money to the coalition, to give it a single mega-powerful vote.

This would be the the bot.

The person who programs the bot, and runs the account must hold true to the ideals of the coalition, and that's what he means by trusted, I think.
