I did think about that but in their blog post they state:

One may not make unauthorized commercial use of, reproduce, prepare derivative works, distribute copies, perform, or publicly display the Steemit logo or brand, except as permitted by the doctrine of fair use or as authorized in writing by us.

I'm no lawyer but I feel this constitutes as fair use. After all I'm not selling anything. In fact I'm giving them away. We'll see how it goes. I hope they are ok with it. If they are not and they complain then I shall take them down.
