Now that you've mentioned that, I wanted to share something else. It's old, I know but it's regarding this theme. These are 2 different designers and one of them is Pro but the vector is the same as you can see. Let me know if you can open the link because this contest is very old. I have noticed that before but I think that forum wasn't active then.

In my opinion they used a vector stock. Bad impression

I checked and I think both from Indonesia and may be work together or possible to have designer multi accounts , thanks
