Ballot stuffing is one of the banes of online surveys. One respondent with a desire to skew a survey can be quite successful, by submitting multiple responses to the same survey.

At Papaya Polls we have a variety of methods to minimize the effects of ballot box stuffers. This includes the standard "cookie" checks, plus a few things that we'd rather keep secret.

The ultimate in online survey anti-ballot-box-stuffing features is our Private Survey tools, which are described on another detailed feature page.
