Have you considered that you’d have more karma if you didn’t post comics with artists credits deliberately removed, and instead just ate a big steaming bowl of shit?
Not the original comic.
Yeah, the original comic actually credits the person who made it.
Downvoting everything you post until you stop posting AI trash of other people’s work.
How exactly are you going to block porn comics when they’re done by different creators, and often reposted? Disabling nsfw isn’t great, either, because it’s usually a global account setting, and people are setting posts to nsfw for all kinds of bullshit reasons. And finally, some nsfw comics are genuinely good! Wouldn’t want to miss oglaf or extrafabulous. TBH, general comics communities like this one are deeply flawed when it comes to filtering; the way they’re set up, it’s often impossible to filter things out even if you were on piefed, which has much more powerful filtering options than lemmy.
I think in this case porn comic is an allegory for beep themselves. If everyone is so upset at them, why not block the account? And that people get off on harassing them.

Because the downvote squad ain’t going to let this behaviour slide
Can you even block banned accounts?
Yes.
Your porn comic equivalent is the negative vote tally
