IMO, he was being kinda mean, and his lashing out at the people who blocked him is a bit mean. (This doesn't mean that a person who doesn't have too many bad intentions getting mad at the adimn who blocked him is bad - I'd be mad for at least a few seconds myself. But pretending to be Cloudy176 - and completely failing, I can safely say Cloudy wouldn't write like that - is what got him in trouble. To be honest, I probably would have blocked this anon by now if I had admin rights - if nothing else, for being a semi-sockpuppet.)

Yes, Superman does seem to be banned. If you go to Wiki Activity, and click where it says "See all activity", it takes you to "Recent changes". There's then a place that says "Logs". Click there, and you'll get a page titled "All public logs". There's a popup list of specific types of logs you can view (such as deletion logs). If you select block log (the first action after all logs), you'll see a list of the most recent blocked users. The first item on that list is (copy pasted from that page):

13:25, July 8, 2017 Cloudy176 (Talk | contribs) blocked Superman37891 (Talk | contribs) with an expiry time of indefinite (Intimidating behaviour/harassment: Also some mainspace vandalism)

He might or might not be the type to create alternate accounts, but that one is banned forever, it seems.
