well, the difference between being blindsided and being farmed is that we already have mechanics and AI-related changes meant to alleviate the kind of farming we have seen over the last few years.

the only solution to blindsiding is political (short of MAJOR changes to game mechanics that change the nature of the game drastically)

I think the main difference between the netters and fighters, in that regard, is that netters pretty much universally realize that farming IS an issue, and want to work towards a solutions.
Fighters generally tend to favour the status quo, or make the argument for netters (or fighters) who are blindsided is to "toughen up and deal with it" and a general culture where war alliances say "we will not hit our friends, and our friends are all the war alliances!"
netting alliances are only friends until they're viable targets, but war alliances are apparently friends forever.
