Goodbye Instagram, hello Ello

I signed up for Ello way back in 2014, and forgot about it. I literally didn't sign into it again after signing up, but in early 2017 I started getting user following emails. I just glanced through the dozen or so emails I have and most of them feature a nude photo for the profile.
While I'm at work I can't look into this more closely, but I have a feeling these are very similar to the bots that are rampant on Tumblr which have very similar user profile pictures.
