Twitter is also crawling with fun and light-hearted bots that are non-manipulative and generate content for others to consume. I would hate to see any of those bots get thrown off the platform.
If someone has a legit reason to fear registering a bot they run, then it's probably for "not-good" reasons. And in my estimation "not-good" could be as innocuous as those follower-fishing bots.
The "up-to-no-good" bots do no such thing, of course.
