I think that bot check thing is pretty awesome. It's pretty different than many other "bot checks" I have ever seen. (If never..) Only sad thing is if it comes in bad time (like when you're fighting against some mobs), but it will be okay when you get to the safe spot to do the test.
I remember my first bot check test... First I fail'd it but second time I realised how to do it. In the end it is pretty cool.
Botters are not annoying. I remember a bot (probably) using for farming mudosa. I was always fighting this lvl50 dende and he was not moving i was just hitting him and we where bot farming...lucky.
