No one engaged in a BGS war and with some brain cells would do what I've read in this sub i.e. like searching all locations here and there or camping hours in a system waiting for a contact etc. [i.e. a "blockade"]... I mean there's no general case, as depending on the various situations/states certain actions and countermeasures might be taken. Intelligence is also a key factor...System? Yes. Location within a system? Not so much.
I'm not sure how many locations there are in the average system, but between planetary ports, stations, and settlements, there are usually lots of locations where people can get missions from, and most player groups can't cover them all 24/7 in all the time zones you'll probably have to cover . And if you do have enough players to cover them all? You'd probably curb-stomp the opposition if you focused on PvE, rather than PvP.

This is an absolutely right comment. Attack and defence are two sides of the coin but there is the possibility that there's very little convercence and overlap [except for the case of wars/civil wars...] of course there is the chance of skirmishes outside wars but these happens most of the times by a case and not by a purpose. Also, the consequences of PvP engagements do have some degree of impact by disrupting opposition, but such impact also depends on what the opposition is doing (hauling? bounty hunting? etc).Which is a stance I can respect, and actually share. I play in Open first and foremost to have fun, and don't worry about efficiency. Though I do get a lot of amusement out of the notion of "defending your faction via PvP," because it's such a poor strategy if you want to defend a controlling faction.
It is a great way of attack controlling faction, though.
True, but after parties take the rebuys some kind of settlement is usually reached... reason is that one can grind relentless weeks or months doing the same thing away from any human direct confrontation. But when the human element comes in to play, the reaction to a human/human confrontation drives to totally different behaviours.Only if your opposition cooperates by engaging in mass murder, which is only effective if you want to take down a faction, as opposed to promoting a competing faction or any another BGS goal. If your opposition keeps things their activities nice and legal, you'd be doing your enemies work for them, which is much more efficient than doing the work themselves.
