I'll go a bit more into my point since it seems to have been a bit misconstrued here. I'm not claiming that "oh the people of the future are worse then the past, moral decay, blah-blah". What I'm saying is that one specific feature, anonymity, leads to a greater willingness to do bad things. This is because one of the pressures that leads people to fit to what society defines as "good morals" is the risk of punishment, something that is decreased if a person is anonymous. There are a number of studies showing a nontrivial increase in peoples willingness to do things like steal or cheat if they are sure that nobody will know about it. (Interestingly enough it was often the case that religious people tended to suffer less of an increase, often because of their view that God was always watching them).
Sure not everyone that uses the internet to do things anonymously is going to cyberbully, but there are a number of people who wouldn't bully people face-to-face, but will cyberbully simply because of the easy access to being anonymous and therefore belief that they are exempt from any retaliation. You would see exactly the same effect if you compared the rates of people willing to bully in person against the number of people willing to bully through normal paper mail.
It's not a decrease in good morals "because technology got better" or "because kids of today are letting morals slip", it's an psychologically provable increase in the willingness of people to do things that society considers "bad" if they believe themselves to be exempt from retribution, which can be easily obtained in the current world by being "anonymous" over modern technology (as compared to the last big anonymous technology of paper mail, current technology allows for the ability to deliver much more content in the same time-scale, even if the rates are the same). And yes, it's not anywhere close to being a general, widespread effect, but it is a study-proven thing separate from the widespread (and wrong) belief in "moral decay".
