I do think this would work as so if you start to send the same post over again or to many posts in a row it gives you a small pop up saying something like "Oh no! Did you mean to do that remember that -Rules here- needs to be followed. Have a great day." It could either post the message with a censor or delete the previous 'spam' messages. 

Although I'm pretty sure that WoP is already working on something like this it. In that post it stated a word limit and such :D

I agree, we need to recognize our quidditch captains and all the effort they put into their work <3
