For those of you who have checked our papers, you
would have seen that not
only we propose algorithms, but we do extensive performance studies on how
good the algorithms are. We will want to do the same for the algorithms for
fighting sock puppets.
I liked it very much that you spent a lot of thoughts on the robustness of
your algrorithm (I think this is one of its key advantages over so many other
naive karma systems out there) and that in this stage it is already
restistant to many attacks. So I am confident that sock puppet and minor edit
attack (Aaron's maintenance edit analysis is part of it) can be solved as
well by you. :-)
About the proposal by Daniel: time alone does not
cover our full set of
concerns.
I can every day use identity A to erase some good text, and identity B to
put it back in. Then, the reputation of B would grow a bit every day, even
though B did not do much effort.
That's true. The reason is that it takes less effort (= personal work time) to
remove X bytes than to add them. Perhapes some weight factor on different
kinds of edits can avoid this.
