In the end, I'm also going to say nay to this rule altogether as well. Yes there's risk, everybody deals with it and accepts it, yer stuff might be lost, wasted, and destroyed without provocation. Or your base might get fired at from time to time, this now limits how much can happen in-game, when in-game rp'ing should be the bottom line. Thats why you need to build a shield and stock it up. Everytime someone fires a shot at a base now they're going to have to rp it to avoid being sanctioned, and its going to clutter up the forum with useless rp. I'm all for RP, but I'm also for the freedom of anonymity through your actions. You shouldn't need to announce to the world every time you get into it with a base, especially to avoid being punished.
If this rule was really to try to alleviate the stress on base owners when it comes to constant maintanence, or worrying about their bases, I still think lowering the consumption rates, by like.... half, would do that trick. Also, lowering the requirements for constructing the various mods would also make it a bit easier on the head. Yes building a base should be a project, but after its established, unless constantly sieged, it should be a little easier to maintain. Indies would not worry so much about losing a base if it could be rebuilt within a day.
Any base built in house terrirtory, like corpration/military owned bases, are well defended and supplied, and do not need forum rp to save them from being destroyed. Most base owners know how strong their base is and how long their shield will last. If they're worried about losing their CAU8, or bank stockpile, they should not be foolish enough to put it on a base that could lose its shield in a short time, and be destroyed soon after. So basically if the owner can't check in on their base regularly to make sure its still there (or have someone do it), with enough time to SAVE their stuff, they're the ones risking it when they shouldn't be. Play it safe, know what you can get away with or not. Let indies hide their bases adequately, instead of behind a useless rp buffer.
