I’ve made a mistake by uploading SFX to my portfolio and I want to change it and make my portfolio clean. Do you think it is legit to create another account just for SFX? Can I remove SFX from my portfolio and upload them again into new one?
You can ask that they placed to your second account(if you have it or will be) an item either via support. You need to create a ticket and specify in it which items and where to move. If you delete an item, they will not accept it again.
