>>95362819They don't get as much posting, but there's a TON of lurking on the porn boards. Text takes up basically no drive space and reading and posting it sucks up very little bandwidth - media files are where most of the actual bandwidth goes. Every time you access an image or an animation on a thread, that's sucking up a little bit of server bandwidth, and most of the porn boards are just 99% people posting and accessing pics and animations... thousands and thousands of them.
Ultimately, most of the porn boards serve no function. There's nothing on /hc/ or /s/ that you can't get off of any random porn search - scrap em. Most of the anime/hentai boards could be merged together (/e/ can get absorbed into /a/, /y/, /u/, and /h/ can get merged, etc), make the leap and change /gif/ to /webm/ to save on space and bandwidth, etc, and of course kill the archives for all those pages. That'd be a HUGE cut in server costs.
