Ah the quest for a free host that supports flash websites... it seems like you and a great many others are headed the same direction as the forums are cluttered with similar requests dating back to 2004.
Before we get into the whole business of finding a ffree flash webhost, let me give you a heads-up on why it is such a hard thing to find a RELIABLE free host that allows Adobe/Macromedia Flash files:
Free hosting isn't. Someone always has to pay to keep the servers running.
The usual scam you find is this:
Free hosting, no ads of any kind. Rejoice!
The host is just as stated for 30-90 days, and then they redirect everyone's sites to something really unpleasant that pays them a lot of money to promote said unpleasant thing.
They open another "service" with a new domain name, and off they go again... lather, rinse, repeat.
