There is a user in our small community, who had caused a lot of trouble in the past while doing a few sporadic good contributions (mostly when he felt the need to improve his amount of points) too.
These days he is fortunately mostly silent, but I realize that since quite some time already his name appearing in the list of recently active posts is enough to raise my blood pressure even before reading what he has posted ...
How can I keep (or regain) my cool concerning this user?
