In Internet terminology, a troll is someone who intentionally posts derogatory or otherwise inflammatory messages about sensitive topics in an established online community such as an online discussion forum to bait users into responding.[1] They may also plant images and data on networks that others may find disturbing (usually indirectly relating to the individual in person) in order to cause confrontation. While not necessarily related to hacking, such a practice is against the Computer Misuse Act 1990 in the United Kingdom, where mischief is caused in order to ensure chaos is spread.
We have a better way of dealing with private sites in the US and that is referred to as DOS.
Unfortunately , that practice is also frowned upon. So, we rely on self-policing and good manners.
