LOL ahahah so they should reject anything having a flame inside … so i really do not believe in this explanation indeed … the fact of the matter is that u may say that this is not original enough as regard to the wild catalogue of existing logos but this is a different story in the end …
besides , once again, there is a big issue as regard to the typo and many authors, especially for the logo field are not suspecting how much typo is important … in this case the used fonts are not matching with the style of the illustration and in addition they are not imbricating well enough is the “drawn” part … not to mention that the tagline is indeed too thin and thus hardly readable / visible …
