How are you planning to enforce the rule?
Say someone is mapping a song and pretends that he mapped it because he liked it; while in reality being commissionned to map it, how can you prove that he was getting paid to map this song?
Conversely, if someone reports a team member for doing commissions while in reality he was not, how can he (the team member in question) prove his innocence?
In other words, how can you be sure that someone is or isn't doing commissions?
