These questions are already been answered:
*The website was called "Last Measure" because the creator PenisBird (not actually referring to the image itself, but was named after it.) played AIM utility named AIM Invader, who in turn found "Last Measure" as the most powerful one. He and the other members of the GNNA group he was apart of had been continuing working on this version until many start using browsers and are able to block pop-ups (what these sites generally does) and scripts, though some are able to bypass pop-ups in some way. Nobody cared anymore, except us fellow screamer/shock site enthusiasts.
*GNAA's purpose is to troll everyone on internet, usually in a humorous way.
*Because they hate them in a satirical manner (maybe?).
*Jews.wmv is possibly a music, a soundtrack or an audio?
*Basically, people are able to sent emails using scripts.
Epic Trivia
- Lemon Party creator allowed GNAA to add the picture in their malware sites.
- GNAA is not racist.
