There are two different directions you can go in here if you're going to try to be creative in submitting something.
-Their publishing standards are ridiculously low. They've been made to look like complete retards in the past. A notable instance was when someone submitted a fake story about being a strong independent black woman (they actually used this line in the letter) who learned how to drive using Grand Theft Auto, and it got published, but the EiC no less. It was up for months until someone in GG outed it as a fake and posted the e-mails. Go for broke if you want to post try this method. Claim to have trolled Obama, claim to be a mass shooter who saw the light of social justice. If it's ridiculous, there's a good chance it'll be published.
-Or go all M. Night on her, post detailed stories of real trolling escapades of real people. "I was part of a SA trolling clique" "I used my twitter followers to harass people" "I'd post incendiary comments online, then cry harassment for pity when people responded angrily."
Then if she shows interest, tell her you're describing the past of Zoe Quinn, Randi Harper, Brianna Wu or Anita Sarkeesian. You could go more obscure. Most SJWs either have a past in trolling or are actively engaged in it. Chu's made bomb threats, Kluwe acts like an internet tough guy about anyone he doesn't like.
Just pick a designated "safe" target they refuse to cover and claim to be them. You could go even more meta and creatively describe things Gawker itself has done as a company, like the coca cola nazi thing.
