I wasn't gonna say anything earlier, but I could have sworn I saw that cap on deskthority on the banned from geekhack thread ( or a similar one ), posted by ripster, a month or so before this went on. I think it was a reference to iMav's password which was "maverick"?? before rootworm trashed the place.
Ripster also strikes me as the kind of guy that would organise posting from a McD's in different parts of the country.
