Our online spaces are not abstract playgrounds but extensions of our personal lives. Our interactions in these spaces profoundly affect us, either positively or negatively. Just as a kind word can brighten our day, a negative, pointless, irritating or toxic encounter — whether it’s outright harassment or simply unwelcome chatter — can drain our energy and significantly impact our mental health. Blocking someone might seem like a petty act. But, fuck it. It’s a way of standing up for your peace of mind.
