Often you will encounter trolls when online, so here are the options how to deal with them.
1. Ignore
Probably the most simple strategy which requires least effort.
Simply, dont respond or even read what trolls write, or just change topic back to what it was.
2. Respond with positive
-Positive about yourself
-Positive about the troll
-Positive about someone else or something else
Trolls hate positivity. In fact, giving compliment to troll will often put them off balance.
3. Respond with negative
-Negative about yourself
-Negative about troll
-Negative about someone else or something else
I dont encourage this option, but saying something bad about yourself often confuses the troll.
4. Respond with neutral
-Neutral about yourself
-Neutral about troll
-Neutral about someone else or something else.
Neutral is neither positive nor negative, but it confuses the troll because it cant figure out what are you trying.
5. Respond with irrelevant
-Irrelevant about yourself
-Irrelevant about troll
-Irrelevant about someone else or something else
This is considered trolling tactic, so why not use it against trolls?
6. Respond in opposites
Making two contradictory statements one after another does not make you vunerable to attack, rather it shows that you are aware of options.
7. Negate
-Say that certain logic or information is assumption(unproven).
-Disprove logic or information.
-Outweigh with arguments.
-Make assumptions yourself which cannot be disproved or proved.
8. Turn it into positive
Add facts or assumptions which makes the troll's claim work for you to make you look good
9. Counter-option
Write an option contradictive to troll's claim.
10. Ask troll a question
Trolls are often confused by questions, since most of them dont expect that so are unprepared.
