Are there any copyright or usage considerations when creating and sharing Countryball comics from free makers?

Generally, Countryballs are a meme, and the concept itself is not strictly copyrighted. However, individual flags and national symbols are often protected. When using a free comic maker, ensure you are creating content that adheres to general community guidelines, especially if sharing on platforms like Reddit's r/polandball which has strict rules. The assets provided by the free maker itself are usually free to use for non-commercial purposes within the tool. If you modify or add external copyrighted images, you would be responsible for any potential infringement. For personal, non-commercial use within the meme's context, there are typically no major issues, but always be mindful of offensive content and respect national symbols.
