Hrm... Most likely whatever caused your computer to have an issue made it seem like you were using a bot. I presume whatever actions you did resembled some sort of bot-like pattern so the players pretty much thought you were using one.
I cannot for the life of me figure out what you did to elicit that response, given I don't have enough game knowledge to know better, but I presume that some other player around here can figure the specifics out for you
