Why do I give even a second thought to the reaction of other online users (who may not even be human) when I get blocked? They’re strangers. None of this matters. It will not affect my physical life in any way what so ever. My rational side is absolutely boggled at my emotional side. (additionally, I know I’m not the only one but I prefer to ask questions like this in first person.)
Being silenced hurts, rejection hurts. Whatever you were hoping for by writing in that space, whoever you were trying to communicate with, you can’t do it anymore, whatever part of yourself you invested in it, you lose. It does matter and it’s fine to let yourself grieve that loss.
