how i got my account approved: (not me, my friend, i am using that id right now)
add skills that are very less freelancers applying. ex. singing or any other creative skills.
show that you are good at that by adding relative proofs.
you will get approved easily.
after getting profile approved. just get one or two projects fake from your friends for ratings. make it natural and you are good to go. change everything now to your original skill. just do not remove old skill immidiatly. keep it and add digital maketing or whatever you want. and start bidding. do not update everything at once in single day. give it 15-20 days and you will have a working profile on digital marketing. do not over-go with bidding, you will get blocked for that if you do not get any project.
