The only thing I see from your suggestions are cons, no pros..
Cons;
People who have little knowledge how the game works would start reporting people for 3rd party programs even if they are legit.
There are monthly rewards from an official VIP giveaways and despite that, people on the forums tend to giveaway a lot of items and free coins as well.
You already receive coins for playing the game itself and you could also convert event points to coins.
Reporting section would be filled with useless reports just so only could receive awards.
I'm moving this to declined, if an Administrator thinks otherwise, feel free to move it back to suggestion section ~
