I have made a step-by-step guide so you dumb fucks can follow.
click on your username in the top right corner
Go to “Settings” and then switch to the “Blocks” tab
Type in the name of the community you want to block
Save your changes. That’s it! See it wasn’t so hard.
Putting the tone aside, I usually browse the All tab for that reason, and also because subscribing in Lemmy is weirder than it was on Kbin (even if it doesn’t crash the page like Kbin did). Nothing personal against the communities, and sure, it’s an exercise on patience, but after some time, the results become noticeable as my feed gets fine-tuned into what I want to see.
Do you mean downvoting or blocking the communities? There is no feed fine-tuning based on downvotes on Lemmy, so if you don’t see those communities in All after a while it means the community members just stopped posting altogether, not that the community got hidden from you.
Blocking, yeah.
Thanks for clarifying!
