Hi Fabio,
It’s regretful to hear you’ve experienced negativity within our game. That’s unfortunate and just not cool. Unfortunately, in most multiplayer games that exist today there is a probable risk of encountering unpleasant players.
The Overwatch team is working hard to mitigate toxicity, encourage polite conduct, and foster a more positive community in-game. In the future, if negative players harass you, we’d recommend you report and mute those players in-question. This will alleviate stress and frustration from your experience and assist us in identifying these bad apples.
Blizzard (along with many other video game companies) has joined the Fair Play Alliance, a coalition of video game companies who share research and best practices with each other on how to combat disruptive behavior. We have a long way to go, but hopefully this effort will lead to something productive for the industry as a whole.
I’m sorry you had a poor experience, I wish you well.
