WHO IS ALAN SHORTIS (facebook login bug)

Sorry for the strange title but this is freaking me out.

When I try to sign in to OGS (it used to keeep me signed in but now I always have to enter my username/pw) I always enter my pw and select login but it still puts me through to facebook (i don’t really want to login through facebook). Whats strange is, not all the time but fairly often it takes me to one Alan Shortis’ facebook page. This is creepy idk this guy and he doesn’t have any connection to me but I keep seeing his page when trying to log in to OGS.
