The three meanings are clearly separate. You can recognize the internet meaning from words like 'Forum' (forum), 'Kommentar' (comment), or 'online' (online). The colloquial meaning 'weggehen' (to leave) is always reflexive ('sich trollen'). The third meaning is a technical term in fishing.

He was banned from the forum because he was constantly trolling.
This meaning of 'trollen' (to troll) is a modern loanword from English and belongs to internet language. It is mainly used in online contexts such as forums, social media, or chats.
Manche Leute haben Spaß daran, in Online-Diskussionen zu trollen.
Some people enjoy trolling in online discussions.
In the meaning 'sich davonmachen' (to make oneself scarce), the verb is always reflexive. So you must use 'sich trollen'. It is also colloquial and can sound slightly derogatory or joking.
Troll dich! Ich will dich hier nicht mehr sehen.
Clear off! I don't want to see you here anymore.
The expression 'sich trollen' (to clear off) is derived from the fairy-tale figure 'der Troll' (the troll). It vividly describes a somewhat lumbering or awkward departure, as one might imagine a troll doing.

The drunk man stumbled out of the bar.
to disappear
'verschwinden' and 'sich trollen' can both express that someone goes away. 'verschwinden' is much more general and can be neutral: a person or thing is simply no longer visible. However, it can also be used as a rude command. 'sich trollen' is colloquial, rare, and often joking or derogatory. It sounds as if someone should finally clear off. In everyday language, 'verschwinden' is clearly more normal; 'sich trollen' fits more in casual or mocking situations.

After the last joke, the guests slowly cleared off and went home.
