The problem's we wanna let anonymonks vote too. The IP lock is released fairly soon btw - within a day or something, I'm not sure. There is really no good way to handle open polls on the internet - it might be possible if you need such a thing by identifying people by their PGP key or such, but that makes voting such a large effort that it only works when you have a real motivation and substantial reason for having to prevent ballot stuffing.

Makeshifts last the longest.
