No online interaction is going to be as harmful as a product exploding and taking out your eye. Except in the case of children and pedos, perhaps. But in that case, most responsibility (all, in my opinion) is on the parents to monitor their child's online gaming. Additionally, a system that doesnt require PSN accounts that monitors in game chat for words and phrases that flags for human interception could easily be implemented. Something like that could be caught quickly and dealt with easily before actual damage occurs.
