Some accounts didnt received the airdrops because they got ban. I think the issue might be that they had around 10 posts for the week,  but the quality is very limited or superficial. Like saying things  like, "I have joined the Facebook and Twitter campaign," or "Looks like an interesting project, I will keep my eye on this project." Or "Sounds really interesting, I will keep my eye on this thread..."

They do not have ten for a lack of a better word, ok posts. They were low quality.
