Slashing + Downtime questions

Hey all
Im curious about the ways in which PSO can face penalities on the network.
Are there ways that a staking pool’s operations can be halted by the protocol? Like if my PSO is offline for too long, does the protocol kick the PSO out?

Is there slashing? If so, how can a PSO be slashed? How much are PSO vs delegators slashed, like in other PoS networks?


Also would like to know the answer to this

The only penalty I know of is when you have 2 block producers running at the same time with the same registration.
