I’m using Voyager, as the community name suggests the OP is. Using the AppStore version on iOS which may make a difference.

How are you seeing the split votes? I can only see the aggregate number.

This is correct, you’ll need to refresh the feed to make the block take affect.

I use both Memmy and Voyager/Wefwef and I only have to block once, it works on both apps. Voyager has an advantage here because I can view/edit the list of blocked communities if needed. Memmy doesn’t seem to allow that yet.

You can block the communities that you don’t want to see. Just go to all, click on the community you aren’t interested in then click on the three dots at the top right and select Block Community.

Pretty soon your ‘All’ feed will be filtered the way you want. I’ve blocked a bunch of communities where I don’t speak the language, and a bunch I’m not interested in. I still see lots of new things but it’s a more filtered version.
