In the game, mobs who have been alive for a long time grant bonus XP to the player. As there is currently an economy problem around fine crafting materials (which may have to do with the anti-bot code), a potential solution to this problem would be to give a high increased fine material drop chance from mobs who give this bonus XP, and have drop chances ignore the anti-bot code for these mobs. Bots by their nature will not be farming these mobs routinely (and if they did, they would lose the benefit immediately).
This could inject more of these items into the economy but still reward players who are exploring to farm their materials rather than fighting the same group of enemies over and over.
