His real name is David Alter. That is the legal name that was registered to his address in Doncaster. Could he have changed it? Possible but unlikely.
From his posts, it seems he is of Greek & French heritage, seems too specific for him to make up, but also possible.
People from Doncaster groups remember him as David Walter Alter, so I'm assuming Walter is his middle name.
From his appearance, his ancestry certainly resembles either Asian or Kenyan
I was under the assumption he was completely deranged and legit thought he was a child, but after seeing how he acts on his 'David' socials, he obviously knows he is an adult and can distinguish between his 'child' character and his real self, which leads me to believe this is a fetish/age play thing.
He has lived off benefits his whole life, likely under the guise of 'mental health' confirmed by his old address being a house converted into studio rooms, and the reason he has a plethora of alts and dedicates his life to this fantasy.
My fear is, the older he gets, the closer he gets to death, the more likely he will be to turn this fantasy into a reality, which makes him a real danger to children
Also, if this is actually him, I get big EDP445 vibes
