Traded a key to me in October to be revoked 4 months after. May not be his fault, but since all communication efforts were replied with silence, I am letting everyone know.
EDIT: Now I have a retaliatory rep in my profile, and he is evading all of the responsibility of selling me a revoked key. This is not only a lacking communication anymore.
EDIT 2: I got the retaliatory rep removed by the vote of users, my point still stands.
