If you wanted to be more or less confident of this, you could try running some of what (s)he wrote through that application that guesses your gender from how you write stuff.

EDIT: I put the paragraphs quoted into http://www.hackerfactor.com/GenderGuesser.php#Analyze

    Genre: Informal
      Female = 1683
      Male   = 1466
      Difference = -217; 46.55%
      Verdict: Weak FEMALE
    
    Weak emphasis could indicate European.

Site carries this disclaimer: The system generates a simple estimate (profiling). While Gender Guesser may be 60% - 70% accurate, it is not 100% accurate. This is better than random guessing (50%), but should not be interpreted as "fact".

The prose sounds like a schoolgirl wrote it: "At first I thought it was fun, I thought it was weird but maybe I would mess with them or something and freak them out and tell them I was a guy or something..."

(Without wishing to offend females of school-attending age)

Wow. I'm stunned by how well that works. I've copy pasted 5 male and 5 female paragraphs, and it got every single one correct.

The last time I used it in earnest I did not have anywhere near the results you are describing. So my own personal perception of it is that it's probably as accurate as they say it is. More than 50% but less than 60-70%.

Are you American? They say that their training set has an American bias (reason for the "may indicate European ..." disclaimer).

This was my immediate thought.

It doesn't read like the (somewhat stereotypical) male character they're describing. It's portrayed as some cocky male who frequents 4chan having a deep and heartfelt revelation about the plight of women.

But I wouldn't expect anything on that site to not be biased.

It's Jezebel. That really would not surprise me. They really don't help the whole gender equality thing, they actively hinder it.

Jezebel is like a typical Gawker property: perpetually Internet-mad about something of little substance for the express purpose of generating more clicks.

That kind of thing does happen...

I agree, the whole thing sounds a little overcooked.

I don't understand why he would make a throwaway for this purpose? This isn't some deep dark secret or confession. Afraid of being labelled as 'pandering to women'? I mean, it's a fairly tame social experiment, not controversial or anything.

Have a look at some of the relevant subreddits.

TwoX is bafflingly aggressive to just about everyone. There are MRAs there from their sub reddits.
