I saw this comic on the front page.  You can also clearly see it in this post.

/comics/bobby17/380681/

But when you click through to view the comic's page, it says "User bobby17 does not exist."

If he were banned it would probably say that instead, right?  Should this comic have been deleted when the user was?  Or should there at least be some code that prevents showing deleted users' comics on the front page?

Was it in the random one panel part?

Definitely a bug going on there. Comics don't get deleted when someone's banned, they just get hidden in case someone needs to be unbanned.

Yeah, it was the random first panel on the front page.  Tried to click through to read the rest and there was nothing there.

It's hard to keep a good bobby17 down.
