It's not a bug or abuse in any way shape or form. This does not break the rules in any way and does not deserve a bug report.
He's just clicking it before you do, you could just spam click as well, it doesn't take that much effort. There are also 2 locations at which you can kill blue dragons, rimmington dungeon and barbarian dungeon. Being new does not entitle you to anything, if someone else is killing more dragons than you are this is completely fair.
If you have any questions about making money then you are free to contact me ingame.
