What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 150 Stack Exchange communities.

I and my friend are both members of Stack Overflow. I told my friend to vote me up. He upvoted almost all of my questions and answers. I got almost 150 upvotes. On the next day, when I visited Stack Overflow, I found my reputation as it had been before the upvotes.

How does Stack Overflow identify, differentiate, and track dummy/unnecessary upvotes?

What? There's no collusion tag? – Peter Ajtai Aug 11 '10 at 23:15

In fact, we have a whole community who does nothing but help us figure out statistical anomalies in voting.

Wow. What an interesting way to promote a SE site! :) – uɐɯsO uɐɥʇɐN Aug 11 '10 at 8:04
@sugar: Because someone has answered it and the answer has an upvote. – kennytm Aug 11 '10 at 9:30
Because another anomalie has been detected probably. Don't worry about it. – Tom Aug 11 '10 at 9:32
@sugar, why, trying to hide the evidence when it's too late? :) (thefirstpost.co.uk/…) – Benjol Aug 11 '10 at 10:12
