I have never been in favour of security through obscurity. The fact is we cannot prevent the selfish use of stake. So, after thinking about this for a moment... why not?

We should be careful not to offer too many incentives to do this though. It should be exactly like self-voting 100%. Receive 75% of your daily vote value; no more, no less.

Also, what about taking those "burned" curation rewards and distributing them as a proportional bonus on curation rewards across the platform? This would provide a boost to curation, to further reward those who decide to continue curating.
