Fraud Bot: what do the colours next to each name mean?

Hello,

I have run the fraud bot on my photo competition and it found quite a high number of suspicious votes. I have a few questions:

1. What are the colour codes next to each suspicious name?

2. The people voting for the competition are from the same school. How much does voting from a single IP or single IP cluster (the school) influence the fraud bot?

Thank you.

I can only reveal this much: Fraud Bot doesn't need IP addresses to find suspicious votes. Therefore, your school's network does not affect Fraud Bot's ability to function.

Think of the colors as a kind of DNA of the people voting.
