I’m thinking of doing a Sweepstake to promote my product and I’m wondering if there is a way to detect spam from auto-submission services like acuwin.com. I want people to see my product page before entering the sweepstake, instead of a bot doing it for them.
How can I tell, from the server log, that a bunch of entries were done by one of these services ~ would the entries originate from the same IP address or do they have a way around that?
Thanks,
