Just as a note, the Pub Halls / Lost Halls Discord is basically its own separate entity. Whatever happens there that you need help with generally isn’t something anyone here on the Realmeye Forums or practically anywhere else can help with, unless a staff from that Discord just so happened to be browsing around (and even then, I’m sure they would prefer that you use the appropriate avenues to contact them, aka their modmail or PMing the person who they asked you to PM).
Interesting that you got blocked from verification due to a previously blacklisted name… usually they block verification due to suspecting an alt account, but that doesn’t seem to be the case here. It could just be the bot glitching out or something, or maybe you do have prior history you haven’t shared…
