There is no reason for a bot to be able to access or post on federated social networks if the goal is to make social media humane.
For this reason, bots should be heavily disallowed from posting content to or accessing content from federated social media.
A bot that masquerades as a regular user and posts paid marketing content once a month
A bot that posts political articles with tailored sensational/biased headlines
A bot that records all activity on an instance and creates a topological graph of the activity tied to users and the content they interact with
A bot that posts a picture of cat, a picture that anyone can fucking google or something that nobody needs or asked for
Who fucking cares if you can come up with harmless “good” uses for bots… they always come with the bad.
Sounds a lot like people.
That third bot sounds really cool honestly. Possible privacy concerns, but not necessarily.
