i don't have specific download which people are leeching, but I have a database which produces pages which people are leeching and stealing my bandwidth.
I think I need to stop people accessing a certain amount of pages per day.
But I don't want to stop google bot or the yahoo bot.
I don't mind paying a small amount for commercial protection, $50 perhaps.
But I think the solution need to be PHP / MySQL based, I think.
