Oh yeah, I love these kinds of dev blogs. Everyone’s been speculating that this is what happened, but we finally got confirmation that some ridiculously awesome steps have been taken against the #1 scourge of EVE.
In the weeks and months building up to June 22nd we monitored and analyzed activity of ISK sellers, and in particular, their supporting groups of macro-miners, ratters, mission farmers and other RMT related units. The information obtained by this research was then used to identify further RMT type accounts and to prepare lists to process in the action. The preparations also included identifying various items of interest that we wanted to monitor and measure, such as market activity, server performance, petition trends and so on, as our intent was to examine the effects of the action in a scientific way and in as much detail as possible. Finally, a lot of work was put into gathering information on and collecting lists of RMT type accounts to be targeted in the operation.
That operation involved the mass banning of the aforementioned nitwits from EVE. Go now, smiling, to the dev blog that contains all kinds of happy charts.
