Shaming people for violating valid social norms is absolutely decent behaviour. It is the primary mechanism we have to establish social norms. When people do bad things that are harmful to the rest of society, shaming them is society's first-level corrective response to get them to stop doing bad things. If people continue to violate norms, then society's higher levels of corrective behaviour can involve things like establishing laws and fining or imprisoning people, but you don't want to start with that level of response. Although putting these LLM spammers in jail does sound awfully enticing to me in a petty way, it's probably not the most constructive way to handle the problem.

The fact that shamelessness is taking over in some cultures is another problem altogether, and I don't know how you deal with that. Certain cultures have completely abdicated the ability to influence people's behaviour socially without resorting to heavy-handed intervention, and on the internet, this becomes everyone in the world's problem. I guess the answer is probably cultivation of spaces with strict moderation to bar shameless people from participating. The problem could be mitigated to some degree if a Github-like entity outright banned these people from their platform so they could not continue to harass open-source maintainers, but there is no platform like that. It unfortunately takes a lot of unrewarding work to maintain a curated social environment on the internet.

In a functioning society the primary mechanism to deal with violation of social norms is (temporary or permanent) social exclusion and in consequence the loss of future cooperative benefits.

To demand public humiliation doesn’t just put you on the same level as our medieval ancestors, who responded to violations of social norms with the pillory - it’s actually even worse: the contemporary internet pillory never forgets.
