This issue can happen by number of reasons, but the most common one is people being tricked into giving their account to scammers.

- Vote my team scam.
- You have pending ban, or I reported you.
- You won, or I gifted you something.
- Invited you to playtests/beta.
- Let trade on this site.
- Using Gambling site / trading sites.
- Sharing account with someone that fell for one of above.

All those lead by scammer giving you scam link that looks exactly like really with alter url address, or using fake windows tab to display a virtual browser to their own server to trick you.

Another way can happen.
- You downloaded virus from discord, or etc places without being careful online.
