So this is the new Russian commercial project http://studyboom.ru/course/dizayn-interfeysov-v-sketch-3/ and we can hear watermarked audiojungle previews in the intro of every available video lesson there. I think this is wrong, but obviously I don’t have rights and time to deal with these guys, so may be we can find the author of those aj items and let him know, or envato staff can help somehow.
We can hear the watermark, but I wouldn’t jump at conclusions too fast. It wouldn’t be the first time that a video editor, having bought the legal licensed version, forget to replace the watermark one in his project. If it was done on purpose, then, of course, it’s wrong, but it could also simply be an absentminded human error…
