I have been seeing many, many articles lately that are using copyrighted images. Some are attributing their sources, others aren't. Regardless, these authors are still profiting from other people's work. This is a worrisome trend for the platform as a whole. Not only is it unethical, but if it becomes prolific the right lawyer could bring down the entire platform.
In early days of SteemIt these things were explained to newbies—in no small part by @sykochica's efforts. I think we are going to need a massive effort to correct this problem. Alas, I don't have any good ideas for either training or moderation. If you have some, please leave them below.
