Pretty obvious stuff

Debate is won through good, well researched arguments, not technical "tricks". Don't claim drops when they didn't happen. Make sure you clash and explain why you won clearly - what did the debate come down to?

I'm not particularly interested in a statistics fight. It is impossible for me to know which statistics are more accurate.

Don't spread. It's not fun, not in the spirit of debate and has zero life skill or educational value.
