my idea to fight referral spam

today i was trying to remove the referral spams i’ve been getting. i found there are so many that it will be way too time consuming to remove them manually. while i do not want to completely rid of my referral script, i can no longer stand all the horrible porno referral spams i’ve gotten. i’ve been thinking about an efficient script to prevent them. many people have already talked about different ways to fight them. [referral spam removal] but i just think making a block list is too tedious. so i thought of a different idea. i will share this idea and some php code with you but this might or might not be what you want to do. the appoarch will increase your bandwidth. i installed it today so i don’t know how much bandwidth it will eat up. we will see.
