if someone wants to boost a post's ratings, so what?? But in general, even with zero security. Any knowledge about the value of a post is better than no knowledge.
Just block an ip for 5 minutes after the vote, if the guy wants to come back every 5 minutes, so let it be
I am still convinced that with rating in place we could easily find all the important posts with the important hacks, just by a simple search, maintenance free (the board owner does not need to archive these posts).
Voting works on other boards, cnnfn.com votes for stock to buy and sell, why should it not work here?? Why does the voting script work and the popularity per post would not work?? What is the difference??
voting for registered users only would be an interesting option, that would be almost foolproof.
