13 posts and 7 merits. Your posts are too high quality (it seems because I don't know your local language, I guess based on what you wrote in English and length of your posts in local board). Length of post does not guarentee post quality, but it seems you made quality posts, too higher than other newbies.
I don't think you are new here.

Some things managers likely consider when screening applicants to choose participants:
- Post history to check post quality
- Trust Flag history
- Language: mixture between English and local; or purely English
- Average posts per day/ week
- Inactive or active posting in recent weeks
