While looking at #16682, @jnewbery noted to me in person that we should probably remove the banscore knob.
My thought is perhaps it could be replaced with a more useful debug flag like -ignoremisbehaviour.
Is there a use case to allow a wildcard ignoremisbehaviour for all peers? It might be better to have a per-peer flag(s) that can be toggled (similar or identical to net permissions) for known peers or peers controlled by the user themselves.
@MarcoFalke I can't think of a usecase for that. I think we should just close this issue now that banscore has been removed.
