Underground players on Dynamis DC tagging mobs. Are these hackers?

No. Just no.
They could create a simplified singe floor topology map for key locations,where this would work. Which is most places.
Like market boards, like certain nodes. Like parts of exploration zones where there are no cave systems.
No one is asking them to solve the problem for all locations like the whole of Limsa with it's spiral stair cases.
They wouldn't need to check often because they wouldn't need to catch everyone. Just every transgressor some of the time.
You can use a reduced snapshotting system. Crikey they use that for all the battle.
Rubber banding doesn't need to happen because you don't need to prevent the act, only need to penalise as soon as possible after. (and even this assumes that prevention does need to have a substantial cost)
This kind of pseudo authority pseudo engineering has been so damaging.
I don't want to fall out with Jeeqbit but it's all getting too much. Some people just accept this kind of absolute certainty as gospel, and it's not true. It's rarely true, it's software.
It can only ever be a discussion, not a declaration.

This kind of statement can only come from CB3 devs. (I won't go into whether they'd be convincing)
Although I have on many occasions wondered if Jeeqbit isn't SE Community. If they are though they need to reject 'some' if the info-policy they've been provided and ask for proof/justification.

Yes, it would require some development.
Some code would need to be added.
Some code would need to change.
There will be 'some' compute cost.

But this whole 'it can't be done' thing is silly.
Yes they will eventually find another exploit. But in that case why ever bother banning any bots at all ever then? Why ban RMTers? They same people will always return.

Not really true. It could come from any developer that has programming knowledge (which you will find a lot of players do, especially in 2025). All they do is put their programming hat on and predict the potential issues that would occur - which is a fundamental part of programming. If someone can't anticipate potential problems, then they shouldn't bother trying to become a programmer - not everyone is capable of it, it's just something they're born with.

But this whole 'it can't be done' thing is silly.

Then why do all MMOs have this problem? Surely some of them would have "won" this battle by now.

That's true and you are correct that banning them is not very effective. If they have 100 bots and they ban random ones that get caught (let's say 3%), it's not really a big blow. Additionally, banning them immediately informs them of what they did to get detected and they can work out how to avoid detection.

So that's probably why they ban in waves instead. They detect the violation, then wait until a certain interval and ban the backlog (let's say 75% now) that were detected, so they can't figure out what got them detected as easily. By banning lots of them at the same moment, it's a bigger blow to their operations.

But it could be an endless cat and mouse game so most likely MMOs don't want to bother investing endless amounts of money in building a large, separate development team to fight them.
