User insert_number has recently been making some meaningless, borderline-spam posts, including stirring up some irritation on the "Ask the person above you a question, part III" thread, here.
Some examples of the contentless posts are one post on the "The Username Game" thread, consisting only of the ORLY owl (there was also a conversation there he started that I stepped in to stop, though not with a staff post), and the posts he's made in the feedback threads. He's been called out multiple times, by both Azzleflux and Aelanna (and me).
There's also one case of what sort of came off as backseat modding, but really was just more misguided advice.
He's already been banned from chat (the thread is here) over refusing to give his age, and took it to the mainsite in a rather inane conversation (thread is here).
Aaaanyway. I've taken the liberty of sending him a PM. I'm slapping this up for record, since the behavior's been consistent over the course of his activity on the site.
