Just dug up this thread, as the topic of Mirror Go is coming up ever so often, and quite often it is brought by people who are terribly annoyed by their opponents mirroring their moves 
(sry but not sry 4 the laff)
If you believe your opponent is “trolling” you when they mirror your moves, that they are “mocking” you … maybe it is time to ask yourself: Are your moves “good” moves or are they “bad” moves?
