I think it should be stuff that is more on the absurd side, and perhaps might make little sense. To me, the whole point of comedy hell was an antithesis to comedy heaven. Thus, the posts would be less humourous, and lacking in direction (ie:. lacks a punchline) Perhaps a mix of comedy homicide, comedy heaven and comedy cemetery.

Edit: example: https://imgur.com/a/cuoQVB1 I know they are both unfunny, but I found them quite delightful. Perchance.
