In case your serious:

1. Redditor creates r/195 (that was their dorm number), which has the rule that you must post before you leave
2. r/195 dies (i think the og mod just stopped modding, but it’s hard to find info with the reddit blackout)
3. r/196 is created with the same rule

If you find it annoying you can block the community so you don’t see it anymore.
