There are other reasons as well but none of them are to "prevent the spread of stake".
Well, I would be happy if you elaborate on those other reasons as well and even if your reasoning for it is to counter DHF spending, it does prevent the spread of stake.
And for the record, it is not a callout to you individually.
For a couple of years everything I posted and everything I upvoted was downvoted by two large whales. This was why I stopped posting and part of why I stopped curating but a large part of the curation is because in some way I want to counter the massive sell pressure of bad proposals.
Appreciate it.
