Nah, they're doing that combat zone grinding because they can hack it and probably won't get detected (so quickly). If they could hack "trading" as easily, they would do that as well. Or mining.
Yes I agree and the reason why some of these people are hacking is because they want to fly anacondas. I'm not saying make things easier to obtain or cheaper I'm saying professions need to scale. Whilst people hacking in solo might not be a problem now it will be down the line when they all turn up in open with pimped out ships.
There are also credit hacks but as you say too easy to detect. The other credit hack is running 2 or more instances and trading in 2 separate stations without moving. The latest I saw today was a zero cooldown and charge instant fsd with up to 2000ly range.
This is all pretty off topic though so I'll stop with the hacking stuff as fd are well aware of the hacking thread.
