You tried to edit any significant Wikipedia pages recently? Go ahead, I'll wait. If your edit exists longer than 6 hours I will personally wire you $50 through your choice of carrier.

Edits are tracked on Wikipedia through a large and obnoxiously thorough community of fact checkers and editors. Posting random bullshit on there will get it deleted nearly instantly and if you do it again you'll be ip-banned. They don't fuck around with that anymore. Wikipedia is humongously crowdsourced and because of that, is actually probably one of the most trustworthy and accurate information sources we have available to us as a species. Every edit made to any page will be scrutinized by 480 community members within 2 hours and if any of them find you're spewing bullshit without sources it's gone.
