Yes they can, there's an option that disables that too but it isn't automatically selected when banning someone. Having a conversation on his/her wall could in some rare cases yield good results and the person might not do such things again. But sadly most of the time when a person does those kinds of things, they don't care what you say, they just keep raging and try to keep harming the community by any means necessary. As you said, a person who'd change would be an ideal person, sadly that's the exact reason why it rarely happens.
