It would be very nice if people who say "vote for *insert vote option" related stuff just get their sentence censored and instead they get the link to the CubeCraft store displayed in chat.
Though I have my doubts, as context really matters in a sentence and it would be pretty annoying if you told someone "Thanks for voting *insert voting option*!" And you get a link thrown in your face. If there is a way around these issues, you certainly have my vote.
Nontheless, I like the concept.
