That deletions you see on there are items that were deleted and undeleted. Anything that is deleted as of the data dump that those graphs were built on is not displayed. I didn't figure that out until after I posted the graph, and I never bothered to go back and remove the delete/reopen data.

The important point I'm trying to make is take a look at the asked and closed graph lines. When a community has to close around 40% of questions, I think something is wrong.
