There's a third option, which used to be used by [ChrisF][1] on Meta Stack Overflow for quite a while: He would post all of his answers as Community Wiki, thereby rarely gaining any reputation<sup>1</sup>

This could be used as a viable workaround by those who do not wish to gain much reputation. Getting rid of all current rep can only be done via bounty. (or mass deleting answers, but that's not allowed and ought to be undone by mods)


Note that this is an abuse of the CW system -- it's not supposed to be used that way. But I doubt that it's anything serious and it won't make a difference if your users do this.


<sup>1. I believe that the +15 of getting ones answer accepted still applies. But that's a small trickle.</sup>
