One particularly clever fellow has been known to write the word fuck in the Shed. I think this is entirely appropriate in the Shed. And whoever figured out how to circumvent the filter and write fuck in this manner is sort of a wizard.
Agree. The shed, of course, is an opt-in, and comes with a warning. The reason we have the filter in place is for areas that kids can reach with no issue - we want the majority of the board to be family friendly.
