I'm not sure changes on self voting algo MUST BE DONE in order for the platform to succeed.
This issue could be highlighted as something we revere as meaningful (in the FAQ) and best practice reviewed, and left to (for real people) user's discretion; (find bots that offend and wipe account); and everyone should consider further over time.
That may do it.
If not, then yes, algos need to change. As always.
You're right; it may not even be a question once considered seriously; and it may be on the next HF or two...
But that brings up another question; how much testing and consideration should an issue receive, before it is included in an HF?
Only your witnesses know; but not sure they were entirely in control of HF19 either..
