I started just reporting reposts to tumblr staff when I see them. That way the post will be taken off tumblr completely, because even if she WOULD take it down, the reblogs would still be up. Hopefully if you report her often enough, they’ll warn her
See, I’m getting conflicting views on this. I have taken this action before, and it’s worked, but that was a good while ago, and people have said that recently Tumblr have stopped doing this. :/ I guess there’s no harm in me trying, though. Maybe if enough of us report them, Tumblr will do something.
