Alright, I finally got some time to get around to managing this complaint.
I am not going to address the head of staff thing because it has absolutely nothing to do with the complaint. Along with Abosh, me having been staff longer than he has, I do not recall ANY such "oaths" that Hive is claiming. No evidence, no claim; simple.
That being said, here's what I'm thinking on the complaint: Kaedwulf and Delta are both out of line.
Kaed is out of line for being passive aggressive and trying to justify it on this complaint as "I was irritated, but my irritation was justified". Your irritation might be justified, but that doesn't justify you to be passive aggressive and rude to another person. If you have nothing good to say, then don't say it, and please show further restraint in the future.
Delta is out of line for the obvious reason of locking the thread. I can only describe his use of powers to lock the thread as flagrant and nonsensical. It was absolutely unnecessary to lock the thread as a single off-handed comment should not be grounds for locking a thread that's trying to get discussion rolling. I'll talk with the (head) administrators on this matter to see what would be the best course of action to pursue because I do have some serious reservations as a result of this issue.
