FYI -
we're filtering out $0.01 donations from the various statistics on the fundraiser from now on. This means e.g. that http://donate.wikimedia.org/en/node/22 shows much more accurate data now, but also that the sitenotice counter has dropped significantly.
Please, if you see people asking about this in various places on the wikis or mailing lists, explain to them what is going on.
These tiny donations are, apparently, people testing credit cards; they don't give us anything, but they also don't cost us anything. We already have a JavaScript to block them at the donation form; I don't know if there's much else we can do about it.
