Disabled

Disabled is a term used to refer to an account that has all of its privileges revoked. When disabled users try to login to the tracker they will receive a message saying that their account has been disabled and is usually followed with a way for you to contact staff to talk about the situation and defend yourself. Users can be disabled for a lot of reasons but ultimately it boils down to breaking a rule of that tracker.

Common Reasons for Disabling
All trackers have different rules and you are encouraged to read your trackers rules when signing up, however here are some common reasons for users getting disabled:

Receiving or winning an invite from a public community or buying an invite

Failing to maintain the required ratio for an extended period of time

Too many hit and runs

Ratio cheating

Numerous bad uploads including disallowed content, wrongly named content, and content with malicious code

Having multiple accounts (either at the same time or during your lifetime)

Multiple accounts used on an IP address

Using a VPN on the website

Getting disabled on another tracker for one of the reasons above - some trackers talk to each other and share black lists

Getting Re-enabled
The only way to get re-enabled on a tracker is to talk to the staff and have them graciously allow you to come back. Depending on the reason you were disabled, they may allow you to redeem or fix your account but this is not to be expected and happens on a case by case basis.

Your best bet it to just talk to a staff member (most likely through IRC), and be honest with them because they know exactly why you were disabled and don't need to be there listening to you.
