IC has always been about stronger "farming" the weak since conception. The difference now is allot less players. Yes back in the day there was allot of talk about honor and the top fams wouldn't attack the smallest. But, when you have 1k+ active players in a galaxy there are allot more targets to hit and allot more competition, which forces bigger fams to fight for space and have plenty of more equally matched fams to fight with. Unless the game gets re-developed and goes mobile I don't see anything but slow decline unfortunately in players. I started playing about 12-13 years back and it was allot different, but that was then and this is now. That's not to say I condone or agree with top fams hitting the bottom, but that is just how it is now. Even back when there were lots of players, big fams hit mid level fams, which were out matched. But, it usually was a quick grab and leave it at that. With so little players it is just allot easier to ruin ones round nowadays.
I agree in the current state, there probably should be one galaxy, min drafting (enough to play with a couple friends, you can always ally your other friends) and hard to del until you get where you want. I think also the fams should be smaller and galaxy to match. It would encourage more competition imo. It may also encourage, fams with just a few actives to stick together, work together and teach and grow new players (if any come along). Because allot more fams would have a chance to be toward the top, which would (i think) lead to less bored top fams farming the smaller ones. You cant always blame the top fams for farming. They can't always attack each other. The game doesn't always allow for them to be close and with decent shares/tickers to have a decent fight. If some changes like this were made, it would only be a good thing for the game imo. But, i'm an grumpy old man, so what do i know 
That being said you shouldn't hit other fams if they are already at war (unless they start it). But, you can't implement anything to stop it (only the community can). Because as the past has shown if you can do something like a war block, it gets abused to no end. Anyway that's my rant and I promise to go back to obscurity and not bore the masses with my long post anymore
