I feel like a couple rules have been established based on things I and Rexy have done on the server...
I dislike the 1000 block rule. Just let us go out to whereever the fuck we want :/
Yes. I shall let you explore wherever you want and wander all over the country side.
This has the positive effect of:
Crashing the map renderer
Making things hard to find on the renderer
Making me manually render the thing
Making me try to keep the server from falling apart
Increases the backup + time to backup + failure rate
Making our world look like this:

On the other hand, if we limit it to a 1,000 block radius, we'd get a 4,000,000 pixel image instead of our current 282,814,464 pixel image. This obviously requires a lot less ram. It's currently crashing, because if you look in the image above, all that whitespace is calculated too, so the fact that people went one way and then the other, and then up and down too makes the image + ram requirements grow exponentially.
