It's 'bored by', I thought...but perhaps 'bored of' is correct as well these days?
That's an interesting one. I think you can correctly say both.
I was thinking of other words to replace 'bored' such as 'tired'. You would usually say 'I am tired of this' rather than 'I am tired by this'. Unless you are saying that something has 'tired you out'.
