Please do not play tournaments (anything in the compete tab) when you first get your account or it will say this:
Wait at least 7 days (10 days recommended) before entering any tournament. During this time, play ranked to age the account naturally.
When you begin competing, do not place high early, especially in your first tournament. Sudden high placements or region mismatches (e.g., EU account placing high in NA events) can flag the account.
Accounts flagged due to early or abnormal tournament activity may become permanently inactive. Inactive accounts are permanently locked and are not eligible for replacement or warranty.
