I'm using kbin with KDE on a desktop browser. Is there a way to hide posts?

Ex-redditor here, still adjusting to kbin, sorry if I'm asking in the wrong place.

Sometimes I run across a post that I just don't want to see again. It's not offensive or inappropriate stuff, so I don't want to block the user or the magazine. It's just sporadic content that makes me angry or depressed and I'd rather not see in my feed when I pop back in a few hours later.

Is there a way in either vanilla kbin or in KDE, to block a post from my feed? Like today, I've popped in maybe four times today, and each time there's some article with a large outraged screaming Trump picture on it and I just don't want to see it. I want a quiet weekend where I can occasionally check in on the news without raising my anger and blood pressure every time I accidentally run across that particular article again.

Edit: just wanted to thank you all for the help - I appreciate it!
