Couple things.
If you feel that a decision was made erroneously, the thing to do is contact us, send us a link to the message you received, and ask that someone review your case. If you have information that wasn't available to the person that took the action at the time that they did, be sure to include it.
When dealing with irregular or tactical voting anomalies, we're not always at liberty to divulge the means in which the pattern was discovered. Why not? Because that would make people bent on gaming the system even better at doing it next time, which would be unfortunate.
I reviewed every single vote you have ever received in the system, along with who cast them, when they were cast, and access logs of the site around that time. It doesn't matter where these users were coming from, what matters is that a fair number of your posts were hit directly by them, and up-voted in far less time than even gifted readers could finish reading them. Enough similarities exist to reasonably conclude that they were you, or were doing it at your request.
If you can explain this, then contact us and we'll talk about it. We will not discuss it further in public, this is a private matter because discussing it meaningfully means information we normally consider private being mentioned.
