Random thought: Why can't strange curvy letters be automatically read?

The problem with allowing bots is that it raises the barrier to entry. If decent bots ever become a certain percentage of your opponents the only way to win will be to be ridiculously good or to build a better bot. Both of those are hard to do. People unable to do either will go elsewhere for their action. Eventually, someone will release an optimal bot that everyone will use and there'll be no point in playing, you'll have no advantage.
