Pirate gank squads have been happening for years, people just don't notice because either the LNS don't post, or they do post but "LolNS" and thats an end of it. Ganking is an issue that both Lawfuls and Unlawfuls have to equal measure, just because most unlawfuls in Liberty seem to have forum accounts and most lawfuls don't you rarely hear of it the other way around.
As for people engageing cap fleets just to cry gank later I'm still waiting for those bombers from earlier. Turns out engageing two LSC's and an LABC with just a pair of bombers isen't a particularly good idea, who'd have thought.
