If you've done nothing wrong, young Wizard, you have nothing to worry about.
Mr Lincoln investigates each and every report, and we take false reporting very seriously too! Players who submit false reports can find themselves in just as much trouble.
If a player will not leave you alone, I recommend using the Ignore button on the Friends List, even temporarily. Select the player in the game or their name in the chat window and the Friends panel will open. From there you can press the Ignore button. You can choose to un-ignore someone later on, by selecting them from the Ignore List and un-ignoring them.
Most of the problems are in PVP. People getting pretty made when they lose or are losing. Tonight I had to report a guy because he was being pretty degrading to women. Made me pretty mad. But we beat them and they never touched us one time. And we were up against 3 warlords and one commandor! And we where one knight, a sergeant, a vetren, and a private. I think it was funny that they were running their mouths off and talking bad about us two girls on my team and they never attacked us once! LOL
