I don't mind gankers usually as they're game content for me too, but I sense a certain level of schizophrenia here...
- The general advice is to engineer your ships in a certain way to be able to evade gankers, but the ganking happens at the very places where you do this i.e. the engineer bases
- The other common advice (which I tend to agree with, to some degree at least) is to not follow the Farseer but the Martuuk route, but it seems gankers are now camping there too as per the OP and SirGank's posts
So apart from switching to Solo, what are new players supposed to do? They won't 'git gud' from repeatedly seeing the rebuy screen, and the "friendly ganker who helps you by blowing up your ship first" is a small minority, I can tell you that - most gankers don't bother with comms at all apart from further salt mining the victim if the victim allows for it by responding to the gank via comms.
And before anyone posts videos of C-rated Cobra's evading a gank attempt, let's face it gankers run purpose-built ships, and "competing" in those vs. total noobs who can only just about use their docking computers is so ridiculously asymmetrical it's not even funny anymore.
You need a lot of flying practice to escape in an unengineered ship against even a
single ganker in their usually speedy, HP-laden meta-build usually fitted with at least some long range weapons (and many work in wings, go figure), so only those who dedicate their entire playtime in Elite to PvP will succeed, spending a lot of credits on rebuys they do not have at the very beginning of playing the game (i.e. when trips to Farseer & Martuuk are essential activities to progress).
The majority doesn't play that way though, and will either switch to Solo or use the block function, which I've seen recommended very often these days in Deciat or more recently in the systems with the damaged stations. I try to argue against it where I can, but the continued behaviour of some players doesn't exactly make this any easier.
You're sawing off the branch you're sitting on, I just think it's really short-sighted, on top of which base camping is incredibly weak sauce imo.
