I had this thought a few times, and wondered if it did occur. Problem is, though - how would they buy up the funds themselves?
Take all of the current accepted methods in the P2P thread, for instance. You have BoA/WF, GDMP, WU, Netspend, bank transfers, Skrill/MB, Neteller, Chase QP (which is generally frowned upon but still used), Amazon, and gift cards. Unless Lock is going to set up a US rep to pay out for their own skin funds, you can cross BoA/WF, Netspend, Chase, and bank xfers right off that list. Any massive trading done with WU (as we've seen), Amazon, or gift cards would be a violation of their TOS (though it's probably a violation to do one trade...lol). Skrill/MB and Neteller aren't available for US players either.
That leaves GDMP - and I'm not sure that's done all over like it is here in the US. So, unless you're talking about excluding US traders, just right off the jump, it would be impossible to pull off on those merits alone (to say nothing about legality/ethics). There's just no reasonable way for Lock to get money to a US trader for the skin funds. That's why they use shady processors to take deposits in the first place.
So - let's go ROW, then. Let's say Lock decides to buy up all traded Lock funds from ROW players. First off, that isn't going to help much insofar as its P2P value, since ROW players generally have much better options than Lock to play online anyway. How much could they buy up? Are there enough ROW traders to make a difference? Could they set up "Juan Pablo Maurice Vengassa Roberto Gargantuan" with a Skrill/Neteller account for the sole purpose of funding other players for their skin money? I live in the US and have no clue on whether they could or not, or in what location.
This is just my opinion, but I don't think it's the ethics of it that would stop Lock from doing this. There's just no way they
could do it, since I'm pretty sure the majority of the trading pool they'd draw from is US-based. They don't have a way to get money from them to the trader. If they did somehow, they'd be in an even bigger potential mess with US authorities if they caught wind of it. I would think that could end Lock a heck of a lot quicker than their inept policies might.
So as interesting a scenario as it might be, and as much as, in the end, it might help Lock to do it, I just don't see how it's actually possible. Unless I'm missing something...and hey, if I am, nobody's perfect.
