There's really nothing ban worthy about compulsive lying like this
It's just silly and annoying
I worked with a guy like this at my old job
"YEAH I HAVE A SECOND JOB AT A CANDY STORE THEY PAY ME $25/HOUR"
"dude adam I could get you a really nice high paying job at this other place I used to work for, just tell me and I'll put in a good word for you"
Yeah ok buddy, why are you working here then?
Or my favorite: he tells the store director his cousin (or something like that) plays in our state's hockey team, who them asks what his name is. Immediately realising his flaw, he's like "what? whose name?"
