A news website, talked about the advertisement and the entity! It also managed to find some more valuable information. Apparently, 30 people have claimed to have seen the advertisement and 3 of them disappeared with no trace.
They also managed to interview some people who’ve seen the advertisement. It’s just as many of us have experienced. If you are interested, I will be leaving the link here. It seems like they actually managed to get a picture of the advertisement so we can actually study it more.
This is actually getting very exciting! I’ll be leaving the image here too.
