That happened when the forums were attacked. I'm unsure if it's able to be fixed. If it can it's probably an easy fix.
My guess is it is an issue with a config or the actual code that makes it's name custom likes mods setting names of blocks, turning it to a computer-generated name.
It doesn't bother me, probably because ever since I used the forums properly its been that way. But yeah... if it causes a huge issue it probably would have been fixed by now
I didn't even notice it until you mentioned it. XD But it doesn't effect your inbox at all. Just call it a forums quirk.
