People don't change. Everybody is a pervert or a sadist or something. Everybody does something weird when they think nobody is looking. The population is growing, and so there is certainly more going on at any one time, but I doubt the portion is really growing.
To be fair, sending naked photos of yourself over the phone to your partner is hardly "pervert or sadist or something", maybe a bit kinky but that's it.
I was trying to infer that making fun of people from behind the Internet veil of anonymity is sadistic, and it's a temptation for a lot of people at some point or another.
I think it's more like "people like treating other people outside their reach as objects without regards to consequences and when there are bad consequences they feel a bit guilty about it but it's too late anyway."
