The dupe candidate deals about suspensions in general, the essential part of this question is the increase of the network-wide suspension length from 10 years to 30. The answer to the question has nothing about this, except that network-wide suspensions are longer than 1 year.
Digging the SEDE, I've found something interesting.
Well... 2046 won't be tomorrow, I am not sure I will live at the time.
As far I know:
- Mods can give at most 1 year, and only for their site,
- CMs can give at most 10 years, network-wide,
- In the database, 9999-12-31 is last possible date, but it would require direct SQL to set up.
But Hutchinson got around 30 years. It falls into (3).
How is it possible? What could have he committed?
Maybe the system has changed, and even a >10year network-wide suspension is already possible?
