@High Seas,
Quote:As to multiple accounts, is it correct you block more than 1 account per IP? How do you handle anonymizer sites or just people posting from offices or libraries? Thank you.
Now, you are just fishing. I'm not going to disclose particular methods (and they are changing pretty fast right now) but the ways to do that is to look for the particular pattern of votes, weighed votes based on history etc.
So while it will always be technically possible to add an extra vote, it can easily be made as hard as having the user require new IPs and new accounts with history and after all that you can still require that they vote within a certain range of patterns so that they would need to cast a bunch of random votes to be able to have their malicious ones count.
And then we can just throttle it all, so that after they do all that work, they get a limited number of benefits.
So yeah, if someone wants to carefully maintain different accounts on different IPs, and spend a lot of time making their user activity look real on their sock puppet accounts they might get an extra vote or two in. But then again they might not. Either way, there are a lot more normal users than nuts like that, and they'll react to counter anomalies when they get through.
If someone manages to sock puppet up or down a topic, users will probably react. We'll also be watching, and adding ways to filter out those votes.
In any case, you are still just making stuff up.
