My husband and grown daughter use my computer to enter one per person per day sweeps.  Will they think I'm using multiple identities and email addresses and disqualify me?  I'm new to this and desperately need help.

I'm having major problems with this as well in a contest. If the contest is using IP address to find out the identity of the votes, then you an only vote once per day per IP address. Even thought their terms listed, "one vote per person/email address per day" it came down to the wire and they used IP address to figure out the identities.
