Adventure: stop signing my own posts

The source tag credits an outlet Pete is relaying (`ars technica`). On
his own reporting it rendered as a trailing `pete` under a message he
already sent - him signing his own name. Drop Source on adventure posts
and omit the tag line entirely when there's nothing to credit; RSS posts
keep theirs.
