From having designed many survey forms to collect medical info, a good way
to prevent individuals from submitting multiple forms is to make them
tedious to complete.(Its hard to get them to fill out even the simple ones,
much less do them correctly.) You may lose some potential contributors to
your database who bail-out before they are finished completing your survey
but its likely to deter your average data vandal and the total amount of
useful info gained should be greater. Shoot for having a good approximation
of the truth.
