Ewen, if you are the one who released this font, which is possible, why didn't you put the correct info in the naming section of this font? Then nothing like this had have to happen. But you did not.
Please compare the text in the pict with what I wrote in my earlier post, do you see anything different? For what you don't see in the pict have a look at the settings and then tell me where there is any reference whatsoever to you being the author.
Where it was found? You will have to ask Ivan. I guess he found it at Dafont. But that is only a guess. No info on Dafont that the font can/may not be made available on other sites. Correct?
Had you done the same as with Ibiscus ...
