A few weeks ago, some random blogger flooded my notifications with garbage. She’d literally hate-read a dozen of my posts and attacked me for writing stuff she saw as trite and self-indulgent. So you’re right — the best and only thing you can do is ignore/block them. Anything else wastes your time, kills your mood, and drains your creative energy. Every minute you spend on those people is a minute you could spend creating, or recharging your brain. :)
