Sure, there are bots in HS. But we’ve also got CODE going around dealing with those.
But that’s b/c if they programmed the HS bots to run and hide the moment they saw anyone else in Local, they’d never be able to deploy. Too much traffic in HS for that. But the Null bots can use that programming, which is what people mean when they say taking away Local would help with the bots. If they aren’t triggered by a new name in Local, then CODE or others like them could get to work killing them.
And if you’re a legit miner / ratter, then you’ll be cautiously watching your Dscan and such in case. You know, since Null is supposed to be dangerous lawless space. You should be watching your own ass, not letting Local do that for you.
