Huawei Messages Info?

I have recently received messages from a sender called "Info" on my Huawei Mate 20 lite, to which I can't send any answers. The messages are in English and seem to be written by humans (slang, wrong trash, etc.) Now this info at 4 o'clock spoils the new episode game of thrones and my sleepy brain reads the message (which appears as a pop up on the lock screen Now my question: Why do I get this news and who imagines he could spoil 1h 20 after worldwide release of the episode? (I already blocked info, so I hope I will not get anything anymore)

Spam is how this photo sms. Just keep blocked, then nothing happens.
