You are linking to uBlock Origin ("uBO") -- that filter list is specific to uBO. The other "uBlock"[1] (abandonware) does not support strict blocking, which is what blocks SourceForge.
Sorry if I didn't make myself clear, what I was trying to point out is that for ublock origin to block sourceforge the badware risk filter list has to be enabled. Also I suppose this list can used with other blocking software.
Oh and gorhill, much much thanks for your time and work on this.
