Again, IANAL, but it may be in Anthony's best interests to create a corporation or LLC or something so that if something does happen and he is taken to court, his personal assets are protected.
Officers of corporations can still have substantial personal liability. My understanding is that where a corporation really does provide meaningful liability protection is for investors who are not actively involved in directing the operations of the corporation, but in that case the officers are still held responsible. Even then, the investors can lose everything they invested, but not any more than that. (The Berkshire Hathaway annual report a year or two ago went into some detail of some things that happened with an insurance company which didn't have such liability protection for its investors, and it wasn't pretty.)
I believe there is a federal law that says that Internet providers are not held liable for copyright violations that their users make if they follow certain rules for removing material that violates copyrights when it is brought to their attention, but I'm not sure of the exact details.
But I'm not a lawyer either.
Actually it depends on a lot of things. A company can indemnify it's directors and officers for actions taken under authority of the corporation but it is dependant on the fact situation (there is such a thing as the "Business Judgment Rule.") As such meaningful liability protection can be afforded to officers and directors of a corporation
Investors can be totally different from officers and directors and the terms should not be used interchangeably though there are situations where they can be one and the same.
I could post a lot more on the subject but do not feel that a dissertation is truly necessary here.
