Why would expect OTM to do anything about this? It ensures people need to buy more lixs and hence is good for the ongoing upkeep of the game. The fact that players leave just means a new crop will come thro and contribute to the cycle.
I highly doubt that many more "new crops" are on the way. This is an aging niche game and holding onto existing players is the priority. Allowing rampant griefers is piss poor game management. At this stage in the games life cycle loosing any more active players directly hurts the companies bottom line.
