*from the freepic website:
i use standard icons and vectors all the time in my contest designs...
Designing from scratch for a contest is not always economically realizable (i need to work for money too)
Final designs will always be altered or finetuned as the 'client' wishes in case they decide to go with me...
Noted. This was reported by an anonymous source but thank you for the clarification. To be on the safe side, I would make some sort of annotation on your post.
