A Sustainability Feature: Allow a Server Or Private Convo to Auto-wipe in specified intervals

As the title says, this would allow a whole server's channels to auto-wipe every 24h, 3d or 1w. This will make the space the discord takes up on a server automatically even out, rather than always building, building, building. 

I think this would also help you guys, as you would need less server space too. 

This would appeal to those who want to help our environment, and I suspect those numbers will increase in the coming years as people see more and more how everything is harming it, including server hosting etc. Might as well stay ahead of the curve.

This would be great to also incorporate in private dms, as an option. That way nobody is forced into anything, and it is simply an individual choice that can benefit both the company and the individuals.
