Hi, I making a banner exchange script. Members will have to place a banner code on their sites to make banners appear. Some members might cheat by using bots to refresh the page to gain impressions and to waste other members impressions so i wanted to know if bots have ip addresses? because i want to only give member impressions if their visitors have ip. What are the other things i can do to check if members are cheating?. Thanks
