Brand name keywords

How can I legally use trademarked name keywords in articles or social websites?

I believe I can use the trademark name with the trademark symbol and a reference to ownership of the tradename. Am I correct?

How can I use it blackhat? Are there countries I can have these sites outsourced from that can legally evade a company.

I see people abuse this everyday. However, if I do it, my competition will probably come after me if I don't have my I's dotted and my T's crossed.

Thanks.
