I've seen this guy do this twice, the first time I didn't report him because he said "I got out of the hosp early, I don't know how though". The second time i was busy fighting so did't take a screenshot, but by looking at this pic you can pretty obviously see he abused a bug, he's a jounin on final rb, yet he got out of the hosp in the time it takes lightning flash to recharge, which is like 30 seconds or something.
