I see no leap in logic; you flat-out denied the existence of any chemtrails:

Chemtrails don't exist. They're widely debunked.

Hive account@apocaloptimisto and Hive account@transcendfinance showed that chemtrails, or, to be more accurate, "geoengineering" is totally a thing. This does not prove the particular "conspiracy theory" about mind andor population control. It doesn't prove that every contrail is an illuminati plot. But it does disprove your claims that chemtrails don't exist, and that these theories are "debunked". The opposite is true. The dispersal of chemical agents into the atmosphere is common practice for various applications and widely known.

Are we gonna be that internet place where we give people hundreds of dollars for saying that 9/11 was a government plot or that Vaccines are causing autism?

I sincerely hope that Steemit will be the internet place where truth can be spoken to power; where honest, rational and intelligent debate and cold, hard facts are given greater value than the opinion of a thousand authorities.

The Steem whitepaper clearly says:

Steem is committed to enabling free speech and building a free society.

That explicitly includes facts we would prefer not to be true and opinions we disagree with, and I, for my part, welcome that :)
