Vote Rewards

Is there a plugin where I can give a TopVoter Rank automatically when the player have 30 votes? and the expiration is 30 days only

 

I don't think there currently is such a plugin. With PocketVote version 3.0 which has just been submitted you are able to get the current top voters using

PHP:

PocketVote::getAPI()->getTopVoters();

but that alone is not enough to do what you want so you will need some basic programming skills to do what you're looking to do.

 

You can but I'm no expert sorry, erm you could always look at your top voter list.
