I am a South Korean man who created the overwatch signature creation site in the past. For a long time I did not play overwatch. So I did not manage that site. In the meantime, a new hero was added to overwatch, and the hero could not be seen on that site either. Now I started to play overwatch again and fixed the site again. There is a change in the api of battle-net and twitter, so we have changed the function to not use it and reflected the newly added hero. (Ashe, Wrecking ball, Baptiste). The battle-net function and the twitter function may be fixed later.
(This site is a non-profit site. I just put google ads to get some of the funds needed to run the site. But I decided to delete the ad just because it was not effective.)
