There may be copyright issues but it's not clear, certainly not blatant. The post may have been cross-posted and the site might actually get the thousands of users it claims to get. Who knows. My point is that is a gloomy and unknown path.
The good news — if you consider the site a stain on the internet — is that it's clealy in breach of several things (assuming lack of permissiokn) that mean it could be blown up:
- Use of the Ubuntu logo
- Use of the Ubuntu name. "Ubun2" is phonetically the same, and that's good enough for trademarks.
- Cyber-squatting on a trademark means ICANN can seize the domain and hand it over to Canonical.
But only Canonical (the trademark and domain owners) can deal with this. Make sure to let them know via their trademark violation notification form.
Edit: If you're into that sort of thing, it's comically easy to find out almost everything about the chap who owns the domain, including place of work, phone numbers, Google plus account (and public photos) and the other 131 domains that they own.
