The link above is not the same Momo. Though it is a tad confusing due to the numerous usernames, she honestly preferred to be called Momo while being a mod on our PPM tumblr, as well as by her friends and during streams.

She also signed some of her work as 'Momochi' if I remember correctly

I hope that clears up the confusion a bit!

Edit: I misspelled her signature, but it's corrected now!
