How do you convince others that StackExchange is legitimate?

It's impossible to type math on Reddit, as it lacks MathJax. I have to link to http://Economics.StackExchange.com, so that people can read mathematical notation.

But some Reddit moderators are unaware of SE, think SE's spam, and remove my links to SE. Sometimes I can convince them that SE is legitimate, and they approve my post. Other times, they dig their heels in.

How can I change the minds of moderators stubborn as a mule?
