I think a simple "lol" wasn't a great response.
--so let me expand. I've only been around half a month and I can tell there are a few people who are probabilities to having a bot running. Why? Who knows.
Side note: he could have been joking.
But, if true: you can still beat them, it takes time and practice (but if they are lazy, just waiting for the win), it's possible.
My advice: avoid them, have fun, cheers.
