With the constant growth of the popularity of the internet and blogging sites, so too do lawsuits increase in number. For this reason, it is essential that you understand legal landscape for marketer.
Even though the internet allows bloggers to place just about anything on the internet, you must still be careful. This is because of the large number of internet laws that have popped up recently limiting what a blogger or anyone can put on the internet. Besides that when publishing, you must always be aware of the laws that will result in your liability.
What Can a Blogger Be Sued For?
Whether you have a personal or business blog, you should be aware of what can cause you to be subject to legal suits. In order to blog without the harm of being sued, you must know and understand the legal landscape for a marketer.
Five Ways to Blog Safely and Avoid Legal Repercussions:

False Statements
In your blog, you must not make false statements about another person or business. If you do make false statements, you most likely will be subject to a libel suit. You must understand that libel can occur in written form, visual depictions, signs and pictures. For something to be considered libel, it must harm the reputation of another person. Basically, it must be defamatory. Insulting someone or making an offensive statement about a person is not libel.

Copyright or Trademark Infringement
Do not in any way use creative work, trademarks or confidential business information in your blog. If you do, you may expose yourself to legal liability. The intellectual property law makes this illegal.

You should always respect a person’s right to privacy, and never publish another person’s private information. Even if the information you publish about someone else is accurate, you must not publish private information about a person without the person’s explicit permission. Publishing a person’s private information could result in your legal liability. Private information about a person could be the person’s sexual activities, financial difficulties, medical disorders, or medical illnesses.

Full Disclosure
If you’re being paid or compensated by a company to comment favorably about a product or service of their company, you are required by the Federal Trade Commission to disclose your relationship with the company.

Guest Bloggers
If you promise to remove any defamatory content about another person made by a guest blogger at your site, you must be sure to remove it.

Section 230 protects you from being liable for defamatory remarks of a guest blogger unless you promise to edit or remove anything defamatory. If you promise to do something, you must do it or suffer the consequences. If you edit content that is non-defamatory of a guest blogger and your editing changes the meaning of the statement making it defamatory, your immunity under Section 230 will be lost and you will be held responsible.
