actually, yes, any program must be done asuming user is stupid
otherwise, stupid users won't be able to use it and they won't buy it, is this bot to be sold for money? or is to be used by an elite?
if it was opensource f2p, nobody would be able to complain, but yeah, this was sold 25€ with a description that doesn't match current status but I'm sure soon will be reached
so his complain is completelly legit altough his manners aren't adequated
