> you will fail to convince

Convince who? Reasonable people that have any sense in their brain do not have to be convinced that this behavior is annoying and a waste of time. Those that do it, are not going to be persuaded, and many are doing it for selfish reasons or even to annoy maintainers.

The proper engagement (no engagement at all except maybe a small paragraph saying we aren't doing this go away) communicates what needs to be communicated, which is this won't be tolerated and we don't justify any part of your actions. Writing long screeds of deferential prose gives these actions legitimacy they don't deserve.

Either these spammers are unpersuadable or they will get the message that no one is going to waste their time engaging with them and their "efforts" as minimal as they are, are useless. This is different than explaining why.

You're showing them it's not legitimate even of deserving any amount of time to engage with them. Why would they be persuadable if they already feel it's legitimate? They'll just start debating you if you act like what they're doing deserves some sort of negotiation, back and forth, or friendly discourse.

> Reasonable people that have any sense in their brain do not have to be convinced that this behavior is annoying and a waste of time.

Reasonable people disagree on things all the time. Saying that anyone who disagrees with you must not be reasonable is very silly to me. I think I'm reasonable, and I assume that you think you are reasonable, but here we are, disagreeing. Do you think your best response here would be to tell me to fuck off or is it to try to discuss this with me to sway me on my position?

> Writing long screeds of deferential prose gives these actions legitimacy they don't deserve.

Again we come back to "legitimacy". What is it about legitimacy that's so scary? Again, the other party already thinks that what they are doing is legitimate.

> Either these spammers are unpersuadable or they will get the message that no one is going to waste their time engaging with them and their "efforts" as minimal as they are, are useless.

I really wonder if this has literally ever worked. Has insulting someone or dismissing them literally ever stopped someone from behaving a certain way, or convinced them that they're wrong? Perhaps, but I strongly suspect that it overwhelmingly causes people to instead double down.

I suspect this is overwhelmingly true in cases where the person being insulted has a community of supporters to fall back on.

> Why would they be persuadable if they already feel it's legitimate?

Rational people are open to having their minds changed. If someone really shows that they aren't rational, well, by all means you can stop engaging. No one is obligated to engage anyways. My suggestion is only that the maintainer's response was appropriate and is likely going to be far more convincing than "fuck off, clanker".

> They'll just start debating you if you act like what they're doing is some sort of negotiation.

Debating isn't negotiating. No one is obligated to debate, but obviously debate is an engagement in which both sides present a view. Maybe I'm out of the loop, but I think debate is a good thing. I think people discussing things is good. I suppose you can reject that but I think that would be pretty unfortunate. What good has "fuck you" done for the world?
