I think the report function should provide following clickable options:
- Spamming/ Immature Talking (not only adults play GW)
- Botting
- Leeching PvE/PvP
- Scamming
- Wanted Leaving (means only when People left through Map manually, for PC/Energy problems can nobody somethign for, when they happen in a sudden)
- Insulting/ Massive Flaming
- Illegal Selling of Accounts or Ingame Gold
- Retarded Naming/Illegal Naming of Characters *however you want look at it

- Cheating Scum (dupers and other exploit abuser types)
* Anything that anyhow has somethign to do with breaking the Gameplay Rules of GW that I might have not thought about yet XD
PS:
- Hacking: for information to Anet that your account got hacked
