The most common reasons why a user account gets disabled are listed below:
A transaction of yours was flagged
Your account is deemed too high risk or suspected of having committed fraudulent activity
Your Steam account has a VAC ban or Game ban in CS2, which means you cannot trade
In rare cases, our system finds suspicious behavior. As a result, it disables the user from taking any further actions. We also actively ban users for suspicious behavior ⚠️
You are welcome to reach out to our support team if you believe you have been disabled wrongfully 💬
