Recently I came across the question, "Java programming homework help" (need 10K rep to see the link).
It was tagged C++ for no reason so I untagged it, but when I came to submit my edit I came across an interesting conundrum. At the time, it had "help" in the title, which is unlawful now, so the system rejected my edit.
However, the guy somehow had already asked the question with "help" in the title and dodged the filter. I didn't think to check the title because he had only just asked it- it's not like, one from before the filter existed or anything.
So I'm currently concluding that the filter must be inconsistently applied.
help
is only blocked if it's at the beginning of the title, but I can't find a reference for that right now.
