I am of the opinion that artists tend not to pay attention to politics as much. Given that this person has been using bots on and off for the last 6 months at least, perhaps its you who didnt notice? As I've never seen this person in a server chat room, and knowing that he is from a different country, I assume he is simply unaware of the change in the community opinion regarding bots. Now that he has been informed, perhaps he will choose to alter his patterns. I don't particularly like the use of bots myself, but I do feel that if we want to implement a change, it is better to communicate than to chastise or judge.
