Sonia was an OTer with 22K+ posts and his first posts in OT date as back as 2008, Sonia cross forums with both RT and OT (Though Sonia mostly forums in RT)
Sonia has been confused a lot for being a girl mostly because of his name "Sonia" and because he wears the blond bob hair (Similar to the hair MaxStirner and PokemonEevee wears) and once asked for advice from OT to make his avatar look less feminine:
He was VERY good friends with another popular OTer: PokemonEevee, the two would always hang out and were the best of friends. They were one of the most popular Shipped forumers.
As of 2013 it is presumed Sonia789 is deceased.
Sonia789 was popular among RT and a little popular with OT. But in Late 2013 it is presumed Sonia comitted suicide, It was reported by an RTer that Sonia would go to PBS's and make sadistic things and jump off the map every time he respawned
Sonia then cut off all connection with every RTer and OTer by having his twitter and any social media or form of contacts with his removed or deleted.
PokemonEevee has offered to pay 300 Robux to anyone who is able to give her any form of contact with Sonia:
"i am willing to pay up to 300 robux to anybody who can give me information as to where he is now"
"I'LL PAY EVEN MORE ROBUX IF THAT'S WHAT IT TAKES
IF YOU'RE NBC BUT HAVE INFORMATION PM ME AND WE'LL WORK SOMETHING OUT"
To this day, it is still unknown whether he is alive or not. But it is highly believed that he is dead.
