That might be the case for a few on PS4 but the rest of the ganking community on PC and Xbox aren't like that. You say the majority but your sample size might be 20 compared to the over 2000 spread across other platforms. Also being that you don't actually know any of them, how could you possibly know what kind of people they are?
You can say gankers are damaging to the community all you want but it's just not the truth. Open is still just as popular as it's ever been and most do just fine playing in it. Many have been honest about groups like mobius, that it's mostly dead, and seeing another player is extremely rare. I know many players on PS4 that don't share the opinion as you. @Idiot_Savant could probably step in here about the PS4 landscape better than I can.
You shouldn't take personal offense at me labelling gankers badly when I said not all are equal. Pirates have a place, but playing murderer and seal clubber for me stoops low. Especially bad when you find yourself privately harassed by PM. But on the upside, it does lend me a purpose, which is to oppose them and aid others where I can. As much as you disagree with my opinion, I know people who have indicated they're fed up with Elite because of these individuals.
