You can comment in question, post a blog concerning any aspect of gambling in your country, bring referrals to increase the poin.
Sorry, I have not any tips to earn points more quickly. You need to do all the activities by which OC give points.
Make new blog, do comments on existing blogs, make new forum topics, make replies on existing forum topics, make new questions, and give answers to existing questions.
There is no any shortcut for making points in more speed. You will have to give your more times and efforts in order to get more points.
