I have a policy that I tend to follow. Mind you, it's policy, not dogma, there's exceptions and I'm not obligated to do shit.
But I come at every question with a few things in mind, if I intend to answer.
The one that's relevant here is that it doesn't matter if OP is trolling, reposting, posting bot generated questions, or is a bot themselves. Very little matters beyond whether or not I can say something.
Doesn't have to be useful, though I hope it would rise to entertaining or humorous.
Why? Because fuck OP. It ain't about them. It's about the community. OP could be an llm bot, but other humans are scrolling by. Maybe one of those gets a laugh, or finds something helpful, or whatever.
If OP happens to be a human asking a real question, even better! But it isn't necessary to be a contribution to the community.
There's trolls on lemmy that are known to fuck around, and I'll still respond to their posts if there's a point. Who cares if they're seeking some specific response or whatever? I don't, I care about spending some time writing stuff and reading stuff.
I'm fine with posts that are "busy work". The comment section is where all of the threadiverse really shines anyway. Same as reddit used to be. So the post is there to drive community activity, that's a good thing.
Now fakey comments, that's where shit can just go away.
