Online Gambling in Illinois (Illegal?)

According to this article, online gambling in Illinois is illegal. I am writing this post for two reasons. First, I am seeking more information concerning the particular bill that made it illegal, and, in general, any additional information regarding these laws. Several google searches have turned up little helpful information.

Second, I am wondering how poker players from the states discussed in the article (Nevada, Louisiana, Michigan, Illinois, and South Dakota) feel about this issue. Are any online poker players actually being prosecuted for violating these laws? Do these laws change the way you report your taxes in any way? It seems difficult to report income from an illegal activity, although I imagine the penalties for tax fraud are far in excess of the penalties for gambling. Any thoughts or concerns regarding this matter?
