What in the world happened with the Party of Communists USA? (And is the American Council of Bolsheviks worth associating with?)

So if you try to go to the Party of Communists USA website, you get a relatively short document by former members accusing the part of really bad stuff like reporting members to bosses and defending pedophiles.

Said members split and formed the American Council of Bolsheviks. As the Party of Communists USA is essentially dead due to these shenanigans, is the new organization worth working with? And can anybody give any perspective about this whole controversy?
