Hi,

I think the title itself, what`s required from you to send an invite as a user in Chinese private tracker,

1- Power User must register for at least 4 weeks, download at least 50G, share rate greater than 1.05, and seeding points greater than 40,000
Notice rule said share ratio not real ratio PLUS seeding points not karma points

2-Elite User must register for at least 8 weeks, download at least 120G, share rate greater than 1.55, and seeding points greater than 80,000

3-Crazy User must have registered for at least 15 weeks, downloaded at least 300G, shared rate greater than 2.05, and seeding points greater than 150,000

4- Veteran User must have registered for at least 40 weeks, downloaded at least 750G, shared rate greater than 3.05, and seeding points greater than 400,000

5-Ultimate User must be registered for at least 80 weeks, download at least 1.5TB, share rate is greater than 4.05, and seeding points are greater than 800,000

6-Nexus Master must be registered for at least 100 weeks, download at least 3TB, share rate greater than 4.55, and seeding points greater than 1,000,000, VERY VERY popular

I myself took many times to understand these rules, so you MUST pass assessment then follow these above-mentioned.
