Compulsive voting

If quizzes, and even polls, are commonly understood not to be good examples of fair and reliable procedures, when they take place on the Internet people's fears are fully justified, at least until their organizers take their security more seriously into account. Nowadays, many of these quizzes and polls with prizes are being manipulated by not especially skilled people using nearly off-the-shelf tools. We point out this problem by showing some simple ways to exploit this lack of security, and propose some solutions that are easy to implement. The main aim is to point out that these frauds are constantly being carried out and to warm administrators to take actions to avoid them.
