Thank you so much for answering! I had a look on your account and so far you have only one recent video linked o your content stream, you get into the pending list as soon as you have at least 3 videos tagged and linked to your content stream.
I saw on your youtube account that you do upload really frequently, but that your videos are not properly tagged and can because of that not been found by keymailer. I would recommend tagging all of your PUBG videos with the tag: playerunknowns battlegrounds
They should be found then and you go into pending. As soon as you are in the pending list, a keymailer staff will check your account for accreditation
Have a nice day :)
