Imagine being top 99.9% and quitting because you lost some online games
Reading it a second time, it sounds like that user lost over 100 points due to a single loss.
So they were trying to pad their rating using the provisional bump, and got angry when they hit their first loss.
This kind of frustration would go away if he actually worked on his chess ... then he wouldn't need to rely on provisional wins to get a decent rating.
I don't know if it was a single loss that prompted a -100... it's unlikely given lichess's system. (you can't start at 2000, you work your way up from 1500, and by the time you're 2400 your glicko is obviously low)
