I'll have to agree with Pam and Malteser. Items from Sims Store, fan sites or any other place that has it, is considered custom content. Sims Store content is official content created by EA, that probably can't do any harm to your game if you follow the right instructions to install it. Third party custom content is created by players. Most of it is rather harmful. First of all, package files that they come in slow down your game. Second, your game might even crash. Third, it can contain a virus. And fourth, don't want to offend anyone, but it looks unprofessional looking if not done the right way. After all, why would you want stuff not included in the original game, knowing that it's harmful?
