@Those who think this article is in some way irrelevant.
While it is true that, in most cases, you'll be fine carrying on with whatever it is you're doing regarding sweepstakes and the like you should not laugh this off.
If you own a business, think carefully about this next time you fire someone around the time of the world cup, for example. I'm sure a disgruntled ex-employee who knows about this will try to use it to their advantage.
If you happen to be a law firm, or in another other highly regulated industry I am sure that your regulatory body will not take kindly to you breaking the law -- should a client, employee or competitor decide to report you to the police.
There are probably many other situations where this will get you into some kind of trouble -- even if you're never actually charged with the offence in the end.
So, yes, this may be irrelevant to you at this moment -- but, like many other minor laws we all break from time to time, there are situations where this could bite you in the arse.
