What is trolling in internet?

A troll is someone who attempts to start so called 'Flame wars' on forums, or simply tries to annoy other people. This is usually accomplished by insulting the other party, while rebuking any arguments against them with phrases like 'no u'.

However, many moderators and users have used the concept of trolling to infringe upon rights of free speech by flagging and removing posts that have been accused of, or deemed, to be trolling - not by legal determination but that of moderators and public opinion.

Trolling is difficult to identify and can, potentially, infringe upon an individual's right to free speech. The concept of "annoying" people is a subjective one and therefore those with a valid opinion or point of view can be silenced by being accused of being trolls. The users who agree with an unpopular viewpoint, which many consider "annoying", are not given an opportunity to testify on the troll's behalf.

Some describe trolling as an attempt to "create discontent". This idea is problematic at best as there is no judge, jury, or legal teams to determine the intent of a negative or critical viewpoint. Trolling is also sometimes describes as "inflammatory" in nature yet under this guise, moderators and popular opinion can lead to the silencing.

Forum and internet users who express their opinion many times over, regardless of the validity, applicability to a conversation, and varied arguments, increase their likelihood of being determined as trolls.
