I agree we should sticky this. One question though, is Litecoin mining on a VPS' CPU also a bad idea? Gaming servers (VPS) use 100% CPU a lot of the time, I don't see what the problem is.
It's the same thing as bitcoin mining in terms of CPU % usage, just a different algorithm. I doubt a game server actually runs at 100% 24/7, and of you can find a host that will allow that, then have at it. I actually used AWS EC2 with Litecoin and fired up a dozen high-CPU instances at once, but the coin generated didn't even pay for 1/100th of the cost to run the instances.
