According to Wikipedia, Plurk stands for the following: people and lurk, play and work, and peace, love, unity, respect and karma.
Karma points get updated every 4:00, 8:00 and 12:00 so do not expect your karma to be updated every single time you Plurk.
Engaging in Plurk chats helps you increase your karma. Don’t just Plurk and Plurk. Reply to other people’s Plurks as well!
As the karma gets higher, it also gets harder to increase it.
Avoid spamming your Plurk timeline. Try to space out your Plurks. The Plurk admin can detect your account and lower it to more than 1 karma point.
It’s best to have variety in your Plurks. Put a link, add an image or video to attract other Plurkers to reply to it.
To Filipino Plurkers, make sure you’ve already signed up for PhPlurk so you can Plurk through your mobile (for free, if you’re on unlimited texting!) when you’re away from your computer
