How can I infiltrate a subreddit and destroy it from the inside?

There's a sub... a sub that threatens our reputation as being smart and rational people. I won't name names, because that could expose me. Let's just call them a hate group.

Anyway, ever since I was a small autistic child, I've had two passions: Espionage and submarine accidents. I currently work as a professional submarine espionager and am the reason why rich people have to sit in the back of underwater buses.

But that's not enough. Keeping sea trolls at bay is not enough. There is a new ocean for me to defend, known as "le interweb". r/subbie has agreed to aid me in my quest in order to sabotage r/altright because all submarine people are middle-class liberals.

How can I accomplish this?
