Lol. Definition Easter-egg hunt.
A troll thread is the same as a troll post, it has no actual meaning, it does not have any real subject of debate other than how ridiculous the thread is, or if it is breaking a set general rule, such as racism or spamming.
These threads will be closed, as they are not only pointless, but can lead to insults and other useless discussions.
It is best to close them before they reach that limit, not after.
