Yes, the problem is that those people also post propaganda on technology which lemmy.ml also has nice stuff too.

What I did is, using RSS Guard https://github.com/martinrotter/rssguard I subscribed to all topics I am interested. Then I add a filter like this.

var blacklist = [
 '/u/yogthos'
];
 function filterMessage() {
 if (blacklist.some(i => msg.author.indexOf(i) != -1)) { return MessageObject.Ignore;
 } else { 
 return MessageObject.Accept;
 } 
}

So you can block users posting too much propaganda, and you are not going to waste your time on this kind of posts.

Good thing about RSS is that you neither waste time checking new articles, you already get notified. I think this is more efficient.
