I blocked hexbear a long time ago, on my mtgzone and .world accounts, and recently I've seen posts from there on those accounts as if I hadn't.
Unsure if this is an app issue or platform issue. Are there caps to the size of block lists? I don't see a count for instance blocks, but I've blocked over 1000 communities.
I meant Settings in Connect. It's an app specific feature so it won't take effect on the web version.
