As much as I enjoy debates in the internet, I have noticed that certain people tend to engage in tactics that cause the debates to degenerate into slugfests instead of allowing them to end on a civil note. Here are some examples of what they do:

1. Lie constantly. It does not matter if what you say has no basis in fact whatsoever. As long as you can make a counter to any statement of fact or logical argument that someone makes, you will appear to be on an equal level with your opponent.
2. Never bother to provide a basis for your assertions by linking to a credible source of information or providing a reference regarding a matter that is not common knowledge. Of course, if you are already doing No. 1, then No. 2 comes naturally.
3. Engage in the practice of what I call “parroting and nitpicking” constantly: Making an exact copy of your opponent’s arguments and answering them point by point exactly instead of stating a new point of your own to move the debate forward. This has two effects: It makes you appear equal to your opponent, no matter how dumb your statements turn out to be, and it encourages your opponent to respond to you in the same way, taking the debate into an endless circle.
4. When you are accused of lying, just call your opponent a liar as well.
5. Engage in frequent sarcastic insults to annoy your opponent.
6. When your opponent complains that your tactics are unfair or dishonorable, accuse him of not really wanting a debate.
7. If you know your opponent has a short temper, wait until his patience has run out and he has gotten angry and then take advantage of the situation to torture your opponent still more!
8. Never admit you are wrong about anything. Always accuse your opponents of not thinking or of being stupid, brainwashed, ignorant, mindless, etc.
9. Use religion as a excuse to justify your extreme position. If your opponent is not of the same religion, use that fact against him.
10. Keep the debate going as long as possible until your opponent gives up in frustration, allowing you to claim “victory” later.
11. Last. but not least, CREATE NEW PROFILES TO INFILTRATE AND THEN DISRUPT GROUPS YOU WERE PREVIOUSLY BLOCKED FROM, THUS VIOLATING THE GROUP OWNER’S PROPERTY RIGHTS!

If you use these tactics repeatedly, you may appear very successful in debates. But you will also gain the contempt of most people who have a sense of honor and ethics. And that contempt for you personally may also lead to a rejection of your position as well, even if the position has some truth in it.
