The app and website both have "latest" feeds. You don't get that kind of recommendation in that feed. The closest to that kind of thing that I see are the trending topics on the right bar, which aren't in the feed.

From what I’ve heard from people who use Twitter far more than me: the only way to avoid them is to use a 3rd party client for Twitter.

I use Tweetbot for both MacOS and iOS. All I see are tweets and retweets from people I follow. Occasionally someone will go on a rant or tweet incessantly about their fantasy football team, and I mute them for a while. I can also mute words, hashtags, or people.

Now if Twitter removes 3rd party client access, well, yeah, I guess I'll see where my followees go. Or find another source of entertainment/news.

I use Tweetbot after trying Twitterrific for awhile. My only complaint is that sometimes a thread won't work in Tweetbot, and I'll have to open it in the website. If I had to use the website, or the official Twitter client, I'd stop using Twitter completely.

Nope, you don't see those while using nitter.net, an alternative Twitter front end. You only see the tweets, and you don't even have to be forced to login to see them.

I don't receive them on my main account. I do receive them on a less active alt.
