I would imagine that you, like most gamers, don’t read every single word of every EULA you accept. For example, if you signed up for the SimCity beta, you probably missed this:
“It is understood and agreed that, as part of your participation in the Beta Program, it is your responsibility to report all known bugs, abuse of ‘bugs’, ‘undocumented features’ or other defects and problems related to the Game and Beta Software to EA as soon as they are found (“Bugs”). If you know about a Bug or have heard about a Bug and fail to report the Bug to EA, we reserve the right to treat you no differently from someone who abuses the Bug. You acknowledge that EA reserve the right to lock anyone caught abusing a Bug out of all EA products.”
That paragraph, ripped directly from section 6.2 of the SC’s beta EULA, essentially says that if you know a bug exists but don’t report it, EA can ban you from all EA products… forever.
Luckily, this probably isn’t going to happen. It’s hard to enforce and even harder to keep track of. Not only that, but SimCity’s beta only for lasts an hour, and it’s nearly impossible to get relevant testing data in an hour’s worth of playtime.
EA probably won’t exercise its ability to ban people that withhold bug information, but it’s pretty crazy that they even have the ability to. Imagine having the SimCity beta crash on you one day, and then the next day you aren’t able to play Battlefield 3 anymore.
