That's why most "good" trolls are those that aren't obviously being a troll, but rather something like a friend; something that makes you vulnerable to the troll. This is why most childrentrolls aren't good trolls; They tend expect results too soon.
No punctuation, no capitalisation - just three utterly noncommital letters that betray no emotion besides mild amusement. Ain't no response a troll can give to it that won't just seem sad and desperate.
Trolls use weird logic all the time, and that really upsets me and I have to go in and correct logic, but in the end it's troll logic so it's not worth going after. It's pretty difficult to avoid trolls in my case, I can handle it sometimes, but I really let myself go since I just despise seeing logic that doesn't make sense. It's even more difficult since I take everything literally.
