The snow effect was murdering my laptop every time I came here. Instead of continuing to bitch about evilzone.org/snow.js I made it stop.
I use uBlock, and I'm sure the other ad blockers will work just the same. All you need to do is add
evilzone.org/snow.js
to your filter list and no more snow. As for mobile idk. I haven't had any issues on my mobile since the script seems to be polling for the mouse or something and with a touch display it doesn't seem to be as bad.
Anyway, there it is. No more snow, or if you like it this is where it came from.
