Canada (Quebec). Presumed Montreal, as that is the location of his precious McDonalds. The beast was birthed in Laval though, at least according to his own testimony.
Seb is an fat fuck high-school dropout who is as of now twenty years old. His first language is French, which soon becomes apparent when you look at the horribly translated captions on most of the images. His art is atrocious, and he typically responds to any sort of genuine criticism with hostility, along with pretty much anything else his French-Canadian autist brain can't comprehend but can still perceive as a personal attack.
The sad thing is that the mods on Derpibooru will defend Seb because of their own progressive agendas. Seb has as of now removed all of his art from derpibooru and his base of operations has moved to deviantart. Seb enjoys practically every cartoon, regardless of quality. You will see equal amounts of fanart on his various accounts for decent cartoons like MLP as you will for unwatchable Cartoon Network garbage. Seb smells awful, as an alleged classmate has attested to (unconfirmed, but extremely likely to be someone who attended his school). Seb has also complained about people not wanting to be around him because of his odor, and in many photos of him in public you can see other people giving him a decent amount of distance.
>Possible diapers (Roleplaying in such a manner and some images of characters drawn in them, though to be fair the characters are supposed to be young.)
>R63 versions of his own character (Might be a good indication of a budding tranny complex.)
>Collecting stupid fucking lanyards
>Likely to be a furfag
>Confirmed to idolize Chris-chan
>Pedophilia? (Befriending derpibooru artist Rainbow Eevee who is as likely around 14 years old, drawing art of fillies in compromising positions and possibly some foalcon on derpibooru. If someone wants to check the Rome archive of derpi it would be appreciated.)

>Being angry at Anonymous, Anon and Filly Anon :^)
>Threatening people who laugh at his shitty artwork with death
>Stealing drinks in the most disgusting way possible (collecting large drink cups from fast food trash cans, washing them out in the bathroom, and filling them up at the soft drink dispensers)
>Stealing items from other stores (admitted but then refuted in a 'dindu nuffin' sort of fashion)
>Derpibooru profile: :'(
(Site seemed to not agree with archive.today for whatever reason, though someone else might have better luck with it.)
