You mention three different things -- banning, hijacking, and canonical problems. They are different.
Do I understand your problem correctly: the same content is avaliable from both a .it and a .com domain? If so, then in my opinion, you should choose just the one domain that you prefer and have the other domain redirect permanenty (301) to your prefered domain. Work to have only one url for any one page -- never more. This resolves the canonical problem, eventually.
So if you want the .com version to be in the Google index -- then when any user agent (including googlebot) requests the .it url, it should be served a 301 redirect to the .com url
And what happened to the .com domain? was banned or what?
For me google take the .it as the main domain because find same contents and hijacking too. Is it correct?
Very thanks Tedster...
Also, it's common for a new domain to show up for a week or so and then disappear because of the frequently discussed "sandbox effect".
Just work on the new domain, I'd say, both content and links. Watch for googlebot to be sure you're getting crawled and then give Google a good site when the spiders comes for a visit. I would not assume your domain has been banned at this point.
However, the only one who knows for sure is Google -- so write to them if you want to. I prefer not to draw too much attention to a site unless I am sure there is a problem that I can't fix without their help.
