so i thought of this:
as many of u know, drops in general are quite rare. during one grinding session, u might get an average or 0 or 1 drops. SOS drops are even more rare. So, im thinking, whenever you try to pick up and equipment drop, or an elixer drop, or SOS, the game asks u to imput a random code like this:
if its unclear, you can choose to refresh the image to another one. it'll time u for X seconds or some time limit. a legit player would undoubtly enter the code correctly and get his drop. however, a bot (assuming he doesnt babysit), cant enter the code (and those random codes like the ones above are designed to be bot-script-automated proof). therefore, bots cannot get drops, bots cannot get SOS, bots get poor, less incentive to bot. of course, these question boxes will only appear if u attempt to pick up a equipment, jewlery, SOS drop.
also, the game can also record those who repeatly enter the code incorrectly, or those who dont enter them at all. taht way, GMs can create a potential bot list, and do their stuff.
of course, there can be some exploit to this, but hey, its worth a shot.
discuss.
(maybe they can, dunno).
