Different Profile Covers Registration Form/Registered User?

Hi SI Team

I have a new user registered (possibly spam user) for the profile final BUG Network.
Please see the first screen shot.
For what ever reason they have the standard ES Profile picture.

If you go to this Profile and try and register for the profile final BUG Network:
http://finalbug.net/network/registration/steps/1
You will notice that I have switched out this ES Standard Profile Picture with another.
Please see the second screen shot.

How does this happen? It does not make sense!

thanks

Paul
