But I mostly hear people saying they enjoy it. It seems it's just another case of some people like it, some people don't. If we didn't do things that a few people complained about, we'd be screwed. I've already had people IM me after reading this thread saying that they have no problem with me posting in closed threads and that they enjoy it. If I stopped, then they would complain, and then I'd have to start again, since they're complaining, and then I'd have to - you get the idea.
You can't go by who likes it who enjoys it. People would enjoy not having spam regulations, and I'm pretty sure I could dig up a few twits who would like a spam forum. That doesn't make it justified. You have to be completely objective here, and the people complaining about staff spamming up closed threads have a point.

However, you brought up the announcement. I wouldn't complain about people posting in threads they knew would get closed if they were posting something different to "This thread is going to get closed! " Also, if a staffer was to repeat something that somebody had already said - for example, if I closed a thread saying "This is the reason this thread is being closed." and then another staffer came along and said "Haha! This thread has been closed!" then I'd probably slap them on the back of the head. It's not just "oh, they can't post but we can" it's "don't post saying that a thread is going to get closed, just use the warn button instead." If they're going to come up with something witty, so be it.
I'll agree with that. If you allow members to spam up threads-about-to-be-closed as well, then allowing staff members to do the same after it's been closed does not blatantly contradict your own policy.

Now let's just see how much of staff actually follows that.
