There is no "official" way to disable these annoying entries in your feed, but over time people have found secret "tags" that if you put in your mute list, will achieve what you want.
This here is a list of all those available tags. There's no real description of what "kinds" of tweets each block other than the vague name though.
I'm not following this account. Nobody I follow is, and nobody I followed interacted with this tweet in any way. Twitter's "reason" for showing it to me was "Bernie Sanders (Parody) received a reply", which is a bizarre justification for adding it to my feed.
For a moment I 100% thought this was a real tweet because I usually look at the user's handle rather than their display name. Anyway, this encounter has made me decide to take a break from Twitter this election season.
I barely know how to use twitter in all honesty. I'm worried I'm liking too many things and shoving stuff in peoples faces. That's a big turn off on me using social apps.
I would love to block all twitter commercial adverts. Presently I block them on sight and now get only adverts from small companies.
Tweetdeck was created by a third-party developer in 2008. It was and is so popular that Twitter acquired it in 2011 for £25 million.
And then Twitter started slowly shutting down its apps, all the mobile versions of Tweetdeck (Desktop, iOS and Android) were suspended and removed from respective app stores. Only keeping the web version alive altered and modified by Twitter. Tweetdeck also had Facebook, LinkedIn and some other social networking service integration, those were removed too. Tweetdeck is pretty much the best Twitter app for advanced users. Now its alive but we never know what Twitter plans to do with it.
BTW, there's a browser add-on called "Better TweetDeck" that adds some more options to it.
