There is a system-recommended procedure regarding suspensions on the network:
- Written warning
- 7-day suspension
- 30-day suspension
- 365-day suspension
For example, on Music SE, this has been happening to me: (I gotta reveal this to the public here... please don't make fun of me.)
On Dec 8, 2018, I have plagiarized another user's content to my own post. The plagiarized content was removed, and a moderator has warned me about this:
On Jan 6, 2019, I was sockpuppet upvoting on my own posts. Eventually, I got caught and had received a 7-day suspension, and the sockpuppet account was removed.
On Apr 24, 2019, I received a 30-day suspension due to some edit abuses.
On Aug 16, 2019, another series of edit abuses led me to a 365-day suspension which is currently still in effect.
How do moderators cast timed suspension penalties to users like this?
