Spammer = Person that uses skills uneffectively.
Pro = Proffesional player that uses skills effectively. (Usually in a combo)
Noob = Level 1 or 65, a person who sucks and doesn't admit it.
Newbie = A beginner.
Lvl 53 Spammer = Quit Lunia NAO.
And as for spammers being noobs, that's debatable. Spammers choose to take the easy way (spam) instead of comboing(which takes longer to master). Obviously a "Master Spammer"... rofl, won't beat a "Master Comboer".
Btw, in Glunia, the spammers are usually the retarded people that don't speak english. No offense to non-english speaking people. But usually, it's this guy:
FK U *****
SPAMMER
U SUCK
I BRING MY LVL 67

^ Noobs.
