To confirm you are a human and not a bot, you have been asked to perform a simple task. This process involves pressing a series of keys on your keyboard. The goal is to demonstrate that you are a conscious being with the ability to interact with digital interfaces.
You have been presented with two key presses: ‘m’ and ‘l’. To confirm, please press these keys simultaneously for 1-2 seconds, hold for a brief moment, and release.
