Seems that sometime over the past couple of days, there has been speculation that has rocked the very fabric of the T2 industry within Eve - and the problem is no one seems to know if its real or not, CCP won't confirm it, all they will say is that 'we have identified an exploit with POS mechanics'
It seems that since day 1 of the new POS mechanics (4 years ago now or thereabouts) there has been a problem with the reaction system on a POS - by doing certain actions it was possible to break the POS chain of input/reactor/output so that an output silo could be filled with only a minor load of moon minerals/simple reactions - basically the input materials weren't consumed, and the ouput kept on repeating every hour with 1 hour's worth of minerals in the input.
There has been suggestions that 3 major alliances stockpiled the high value R64 moon minerals (or more specifically, their simple and complex reaction counterparts that use those moon minerals) and have basically commanded the market value for those 4 years.
Suggestions were made that as much as 3,000 Billion Isk profit was made by 1 alliance from this 'making money from nothing' exploit which funded Titan projects, outposts and also gametime for those that were involved, basically meaning they got to play Eve for nothing, as they generated the isk to buy their gametime essentially from thin air (or more technically, vacuum)
Other calculations suggested that if this was fully exploited it would have the chance to generate around 406 Billion Isk over the 4 years per POS that was exploiting, but that was a very unrealistic estimate as no one would be expected to be able to sell that much material constantly - but it could explain why things like freighters were found full of moon reaction minerals in the middle of captured POSes during wars.
What will this mean for the man on the street - well, once this exploit hole has been cleared up, it's very likely that the amount of output minerals will drop (as theres apparently no way to get the same amount of input to maintain the same level of output using legitimate moon mining methods, due to the limited number of moons available) which will lead to price rises.
It already happened yesterday, there was mass market panic buying of the moon minerals involved, either for people to stockpile in case of massive price rises, or people who were buying and reselling at a mark up.
Whilst theres some indication of truth to the issue by CCP stating that they have identified and are in the process of fixing the exploit (and removing the POSes which exploited as well as the accounts) many of the more paranoid members who remember the T20 incident are simply stating that this is another 'internal corruption' issue where CCP were in on the deal, and their game-playing alts were involved in an attempt at massive market manipulation to raise the price of their stockpiled minerals to make a profit (for the record, the T20 incident, whilst I wasnt around at the time was to do with a CCP employee using his GM powers to create an unfair advantage for himself and possibly his corp)
The fallout from this should be interesting to watch over the next few days, but if you have your heart set on getting a nice new T2 toy (especially a ship, since they utilise every type of moon minerals somewhere in their components) it might be worth getting it sooner rather than later, at least if you believe the market hype.
