Usually, blocking those people works if you don't want to see those kinds of posts.
Well no, that's tantamount to ignoring a problem.
This is a recommendation thread, not a discussion thread, period, those who flood this place with arguments are in the wrong (Me included sometimes sure, but I tend to clean up after myself within a few days) a discussion thread can be made for your chosen topic if you please, but it's not what this thread is for, especially considering that it'll make the recommendations themselves for the most part go unnoticed, or end up lost to time hidden away between the pages & ultimately forgotten.
So no, "blocking" isn't gonna help that.
Just... Don't flood the thread with unrelated chatter, come on... It's not hard to do.
