I used to run it on an old PC I got for free from a school made circa 2007 with a core 2 duo and 2gb of RAM and it ran remarkably well for such an old machine.
I think the ideal solution would be content warnings like Mastodon has, maybe these convert to NSFW posts for activityPub but within Lemmy surely they can work the way intended.
To piggyback off this, hobby machining in general. You can buy a small lathe pretty cheap but add some decent tooling and oh you need a very fancy tool you don't have? Hand over more cash. You want to make a part that won't fit in your small beginner lathe? Time to fork out for a bigger more expensive one. Oh a mill would be better for that part? Those kidneys could get a basic mill. Oh you need more fancy tooling for the mill now...
For when you just want to shoot the shit
