Not surprisingly, we have found some spammy nomination patterns in the Zeitgeist. Without going into specifics, we found patterns where a few voters are making hundreds of nominations, nominating the same person everytime. This seems to be a systmatic, and very different than normal voting patterns.
We are removing such votes from the system. Future votes from these users will not be counted as well. We have also developed algorithms to detect other types of spammy activities in the Zeitgeist, and will be regularly removing such votes from the system. If you see changes in the nomination count, this is the reason.
Our goal with the Zeitgeist is to find genuinely popular users whose content people love enough to nominate. Nominating yourself or your friend hundreds of times does not count!
