Sorry, I may be a little late on this thread (7 pages in!) however, the site in question does indeed have seem to have pirate copies of the Amiga system files, which Cloanto currently sell (and at a very reasonable price I might add too). The domain is also hiding behind an anonymising agent. All of which comes across as decidedly dodgy.
edit:
I've done some more reading. Franko, sort yourself out. I suspect nobody on Amiga.org is 15 years old anymore.
