To send pornographic images to a cartoon character that's supposed to be for kids is sick. It ought to be a crime. Just because a person uses the Internet doesn't mean that they're giving consent to be harassment and bothered. People should have to be decent on the Internet, and in person.
Poor Tony. I for one am all for keeping the internet free and open for all but the way social media is transforming into a monster is scary. Behind a computer screen, people expose the demons in their souls and it makes the entire internet unsafe. Humans being turn into monsters without regulations, the time might have come for the internet to be heavily regulated.
Yes, there should be limits on what people can send through social media. There is no need for pornography, profanity or bullying on social media. People turn to social media for relaxation, information and communication in their daily lives--children included. They should not be inundated with such garbage. Social media sites have a responsibility to filter what appears on their pages.
It depends on the terms of service for the specific social media thing. If there are age restrictions for the specific site then yes they shouldn't put pornographic images on that site. However, I don't see why it should be illegal. As long as they aren't exchanging child porn. That is the only thing that should be illegal.
