avenging crime - site about US vigilante groups through history?
Avengers tv show - fan site for US fans of the Brit tv show (I used to watch it).
avenger - the automobiles; site for owners. Was also a kit car in the '70's.
crime fighters - might be a nice site for US crime fighting, even an 'America's most wanted' - type thing.
Undeveloped:
resellers - nice word with many uses: low xxx; mid xxx if they're really hot on marketing to a known client?
end users - med xxx to high xxx if they think it's ideal. As with the other thread I was just in (fiance.us), the dot.us both hurts its value but helps define the targeted market, so not a bad name.
Plus, added bonus of 'avengers' being a very cool-sounding word.
