There is a neat little app going around the tells the user if a poster is a member one of those offensive subs with a little tag by their handle. If you're a member of such awful subs as r/conservative, r/whereareallthegoodmen or even *gasp* r/italian people can see it right away.

Thankfully anyone can download it and now when I see my fellow persecuted brothers I give them an upvote even if I'm not a fellow member of their sub.
