Wasn't he banned at one point and allowed back under the new moniker?
I'm also pretty sure he PM'd me once a couple of years ago because people kept calling him devnet and he was trying to shed that reputation.
Either way, he's a pain and he pushes conversations into places they don't need to go. And if he's subtly threatening people, may be worth some kind of a conduct warning to encourage him to pull it back. He is intentionally asinine and obtuse in A LOT of the conversations he takes part in.
