Yes, the commercial endeavor question is a great one. Also, what happens if you do post content and then are contacted by the creator to take the content down and you can't after seven days. I have been trying to figure out how to format for CC licenses for material that requires attribution. You must include author, cc license, disclaimer and one or two other things. I have just been trying to use pixabay CC0, no attribution for most of my stuff.
Thanks for letting me know you did receive the post. Looking forward to your comments.
That is exactly why I try to stay away from google searches for photos and use pixabay CC0 if I'm not using my own art or photos. I don't want to worry about the headache should something like that happen. AND being that our stuff is on the blockchain, should we be given a directive to take it down, you're right, we can't edit our posts (which is something I thought we were supposed to be able to do) and we cannot permanently delete it even if we want to! It's still housed on the block. It's definitely an interesting topic.
