There are some people find the puns irritating.
There are some find them not funny.
They irritate me when people are trying to have a sensible discussion and this is going on at the same time. In fairness it's not always obvious when a thread is "dead" due to the stop/start nature of message board content.
SO .... we had a  48 hour rule last season that said after that time a thread was fair game for puns (the 48 hours was to kind of take care of people who only logged on here using work computers).

For the avoidance of doubt - this rule applies again this season. I don't want to have to sanction anyone over something as meaningless as this, but I will if necessary.
