On the legal side of things everything depends on location when it comes to the internet. It gets pretty complicated considering if you commit this crime you are often dealing with more than one set of laws and locations sometimes countries. Then everything falls down on your data feed and the ability the prosecuter has to find it and relate it to you.

As for the abuse part, its pretty much just like real life situations. The minor has no clue what he/she is truly doing. Doesn't have proper understanding of the situation and many other things. This is a very serious and dangerous things considering how many people are out to do harm in these situations. If they find a true predator things can get pretty bad. If its just another lonely individual then its simply just committing a crime you shouldn't do.

Everyone's expierence and outlook on things is different. So it is a unique expierence no matter who you are and the degree of "abuse" is relative.
