Is anyone else here running a Flash games site and receiving emails from GameSubmissions.com ?

They send weekly Flash Games newsletters with a featured game and top 5 games. They have links to ZIP files and encourage webmasters to post the games. The only problem is, their main web domain says "under construction", and as far as I can tell, they seem to use a "wrapper" that calls 5minutesmore.com. So that leaves me wondering if the games submitted are "stolen" or are they authorized by the authors and submitted to this service.

Can anyone shed some light on this? They don't respond to any emails.
