That depends on if the developer programmed an exception for this scenario what that exception does, otherwise it would likely just crash. As for the developer they’d just make another account for the bot to use, and likely try and figure out where they went wrong to avoid being banned again in the future.

Bots would likely figure it out quickly as they usually work on tandem with other bots boosting their own posts and comments which will fail if it can’t find the other bots content.

Accounts are free and easy to make so if someone’s banned they’ll just make a new one and circumvent the ban. If you are shadow banned them you won’t circumvent it.

Businesses shouldn’t be allowed to purchase residential houses, they can do apartments but no family homes, even if it’s split.

Political donations should be illegal except from a private civilian who must follow all rules and limitations. If a corporation thinks a specific politician is in their best interest the corporation’s then the only option should be employees should be the ones to donate their personal money up to their limit and not funded from the company itself, a business or pact should have no sway in an election and should only be influenced by individual voters. That way the individual can decide if that politician is best suited for the country or just their business.
