It's a person.
He has photos of his cats.
One day in June Q said 'obscure comms'
so he decided to type what he would post as a text composite overlay ontop of his picture of his cat.
and that is Mr. Pig.
It's a person, who occasionally is here and will post.
and becuase he's real it gets coopted and other 'knock-offs' happen.
but it's a person. an individual. One anon with a meme-concept to obscure his comms.
I may be wrong but that is what I see him as.
