So, I was chatting with Swampfall, who decided to switch to
Duskrai, a permabanned account, on the Herochat we were in. I only
decided to speak up when they did, still on Herochat. Then their
program crashed(This had nothing to do with herochat or the bug
btw) right after that and then we moved to PalPad where Swampfall
noted it was just a bug, how they did it is because the bancheck
isn't implemented on both Herochat (what i was on) and the
interaction widget. It's an interesting bug, but still a bug which
should get reported here.
