Sort:  

it can and cannot be, it's a very grey area and at the end of the day comes down to the decision in court - especially if the website being posted on hasn't set their rules, clearly defined such as steemit/steem.

We thus prefer to play it safe, for the sake of habit and influence on other users, keep a consistent quality setup yadda yadda =)

I will be more cautious in future posts. That's a good practice, I'm glad you have implemented this!
