Now see, I dont know why anyone would open up an ad-free FWH. What's the point? Is your goal to create yourself the biggest headache in your life and some time of being purely miserable? It's enough of a headache when you DO have ads! What makes it so bad is the idiots who want to distribute warez and dont care if they kill the host.
I was finally forced to implement additional measures due to warez abuse. Stopped hotlinking, No directory file listings, and then I limited what types of files could be uploaded. Sorry, but an ad based host is hard enough, I just cant understand why anyone would start an ad-free host. Granted the ads dont pay, but what does get the bills paid is that people will pay a few bucks a year to increase their space and get those ads removed as well as be able to hotlink.
So some startup FWH's with the idea that ads dont pay so why have them....sorry, but yes, if you do it right they DO pay. Our free hosting definitly isnt the best(it's for newbies mostly), but it's big and has been around a long time and actually pays for itself...so we must be doing something right.
