# Ban, unban user or chat

To ban the user, use `.ban` **answer/api method** or **Ban class-method**. To unban the user, use `.unban` **answer/api method**. This is an example where we ban a user if they type "\*\*\*\*" in the chat and unban after 5 seconds

Using these methods, you can also ban users who write via chats

import { AppService } from './app.service';

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) {}

  @OnText('****')
  async banHello(@GetAnswer() answer: Answer) {
    setTimeout(() => answer.unban(), 5000);
    return new Ban();
  }
}
```
