Are you using amethyst?
Discussion
primal, amethyst, yakihonne, notes
Then you can use the like button for a dislike button, only problem is that the guys using Damus and Primal would never know.
Only the amethyst users will know when they are being ratio'd and mocked. Lol.
Sometimes it is an advantage to get dislikes, or as some call it constructive criticism lol
