Btw how people get easy rep here?
Could you recall your first ever rep on this forum? just curious
I will answer this particular question since you've got your answer from the two posters, it's easy in the old times, but now you need to build your reputation by helping people find answers and promoting and recommending the right projects and supporting people who got scam and giving positive negative feedbacks to those who deserve it, it's just some of the ways.
Being active on the forum and helping people is one way to get a reputation here.
But another way is just be involved in the Marketplace here on the forum. There are plenty of people looking to buy or sell a lot of things. It might be hard as a newbie for people to trust you in the beginning, but if you use escrow services here on the forum.
Starting to buy small things here on the forum is a good way to begin dealing in crypto currency and building a reputation on the forum.
