Most of the Darwin Awards stories are true. They do a fairly decent job of fact checking.
However, they do tell 'unconfirmed' and "urban legend" stories (the .22 fuse replacement/frog gigging story is one of those).
The list above, however, is not new. That's an older list with a more recent date tacked on.
For example, #4, the lawyer in Toronto 'testing' the window strength, is both really old and true.
It happened in 1993.
