Abstaining also means that you are not informed, or that you are not aware of whats happening. Abstaining may also means you do not agree with the voting procedure and with the budget system as a whole. The budget system was not voted, it was imposed, remember?
Anyway, nobody knows exactly what abstain means.
The interest of the majority is those 1459 to be punished. Let the majority of the masternodes to decide whether they want to punish those 1459 idiots, or not. If they majority abstains, it is obvious that those 1459 will not be punished.
And of course (the most important thing is this) the way the community will vote on this issue will reveal to any objective external observer whether this community is a fraud or not. Because if the majority decides against their interest, this means that either there is a fraud or they are stupid. And this is a very usefull information for any objective external observer (and potential investor).
I'll look forward to your proposal!
