There is a tag, #nobidbot that some people use, but it's not as strict as with some of your points.
- I haven't delegated SP to any leverage initiative that will auto-upvote my posts regardless of content.
- This post will not get upvoted with non-curation votes through any other type of leverage that is under my control.
And so initiatives like SBD, qurator, make-a-whale, etc would be out?
