I am. You’re not getting my point. Hee. Let me try to explain better..
Okay.. when you publish a blog, usually you use a service that resides (has servers) within your country. Even if you don’t use a service (like Blogger), you still need a place to store your files, which also would most likely be in your country of residence. I didn’t know what country you lived in, I assumed it was the U.S.
Now, if it’s just a question of saying bad things about an employer, you probably don’t have to go to such great lengths. If there’s nothing in the employment contract preventing blogging, your friend is free to whistle-blow anonymously about a company, provided what’s said is true. Yay, freedom of speech! It’s only a problem if you’re slandering/libeling, but as I said, if it’s true, I wouldn’t worry too much, other than taking precautions to remain anonymous.
If you think The Man might get involved, you would want to take some extra precautions. I’ll use the example of your friend wanting to post some sensitive, whistle-blower type stuff, but several steps more serious.. something that would catch the attention of The Man (govt.).
So if you’re publishing a blog in the U.S., and you divulge sensitive material (for example), the government could potentially get information easily about the account owner and also very easily nab you, because you live in the country where the rules were broken.
However, if you live in the U.S. and use an overseas/foreign service, or store your files on a server in Poland or something, it makes it more difficult for you to be tracked down.. the country may not cooperate with the demands of the U.S. government to reveal the customer name, it would make it more difficult for the files to be subpoenaed or whatever, etc.
See what I’m saying? Add in the use of some proxies and you can at least somewhat distract the authorities on where you are exactly. I’m not saying it’s foolproof, but it’s smarter than just using Blogger and saying a bunch of stuff that could get you in trouble. ;)
