Ok so this is a way you can use to usually know what the person's main focus is in minecraft.

PVPERS: they are usually the people you see around pvp on a server or on a pvp server. They usually are more aggressive toward players and typically like calling players Noobs, and sometimes bad words if you are bad or just not as good as them at pvp. They are usually the people with the Diamond stuff.

BUILDERS: They are usually the people you find on plot servers, and tend to have the coolest houses. They usually are willing to help players with their builds once they are done with their own. They could get BUILDING RANKS on servers that have them and they are usually that one staff member that is really good at building. They usually build big projects and take very close attention to detail.

GREIFER: They are usually the people who don't talk or interact very much with other players, They also tend to play alone. You can probably notice who this kind of player is also due to players online that say he/she is a greifer.

SCAMMER: They are usually the people that try to ask people to pay them money then they give you the stuff that you want. But when the person takes the offer the player pays them but the SCAMMER doesn't give the item that he/she promised. They also will do the opposite where they ask for the stuff first and then they pay. They usually don't have a little shop where they do the SCAM they usually just tell you to meet them somewhere.

THE DEDICATED PLAYER: They are usually the player that you see on the server ALL THE TIME, they usually are very social toward players since they get to know them due to being on a lot. They also are sometimes the players that like to report other players for not following the rules. They tend to be the players that will probably become a STAFF MEMBER. They tend to have lots of friends on the server and seem like they know EVERYONE the staff members usually like these players and hang out with them.
