A note on harassment:
A large part of what makes things harassment is that it is uninvited. Which means that if you engage someone and continue to engage them, when it's clearly unwanted, then it's harassment.
Now, the thing I want to focus on specifically in this case is the contacting of Masuda through social media. I want to focus on two things:
1) It is against twitter TOS to abuse the reply system to spam an account. That can be considered targeted harassment and can be actionable (Yeah, a big surprise that Twitter actually has rules!)
2) There are times when direct action is necessary, even when it's messy. Protests live or die by how much they can disrupt. But this is a game. It's not...really a big deal.
Don't be that person who resorts to harassing an individual because a game didn't do what you wanted it to. Go write a comment on the Pokémon YouTube. Dislike their videos. Make silly memes about Dexit. Tweet to the Pokémon twitter. Whatever.
But don't harass people. And definitely DON'T justify harassment just because it's "not serious". Specially not on ERA.
