Maybe you clicked on this video by accident, and the system will automatically default that you like this video and send it to you. In fact, if you don't like it, you don't need to click it at all, or there is a cross in the lower right corner of the video after clicking it. You can click on it directly, and it will tell you that this message has been blocked. Disliking is the poor quality of the content. If you have seen a similar one, you can choose one at will and won't push it to you again.
