No, as long as it's personal or entertainment content (not commercial) :)

Sure thing! You don't need to credit as long as you don't generate revenue from your posts, if you do, just add "Emoji by bluemoji.io" in description

Yes, but only if it's not solely for commercial purposes, for example if you create funny hats all the time and bluemoji can be a good fit in your established products, then you can sell with minimal or same price like the rest of your products, bluemoji can't be more expensive then the others, and attribution "by bluemoji.io" is required. If you are new creator and hoping to get a boost by releasing bluemoji assets with some revenue - it's forbidden. The license agreement does not permit the exploitation of bluemoji Icons for individual profit without incorporating them into a larger work or established product line.

Unfortunately no. But you can contact me and explain your idea and maybe can figure something out.

High quality joobi available in individual request. Please contact me and explain why you need them to be so huge :D

No, however, if you are an established creator who consistently creates for ex. funny or meme t-shirts, incorporating bluemoji can be a good fit within your existing product line. In this case, you can sell the t-shirt with a minimal or similar price range as your other products. The bluemoji should not be priced higher than the rest of your products. Additionally, it is required to provide attribution by mentioning "by bluemoji.io". The license agreement does not permit the exploitation of bluemoji Icons for individual profit without incorporating them into a larger work or established product line.
