The most egregious example of this that I have seen was this tweet, just the other day https://twitter.com/BernieeSanderrs/status/12197474935308328...
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.
