-Back in the day when file sharing was new, I won two rounds of beer from my friends in university - the first after I tried what I dubbed hardcore backups (Tarred, gzipped and pgp'd an archive, slapped an avi header on it, renamed it britney_uncensored_sex_tape[XXX].avi or something similar, then shared it on WinMX assuming that as hard drive space was free and teenage boys were teenage boys, at least some of those who downloaded it would leave it to share even if the file claimed to be corrupt.

It worked a charm.

Second round? A year later, when the archive was still available from umpteen hosts.

For all I know, it still languishes on who knows how many old hard drives...
