You need to unlink your feeds.
I understand why you did it. I’ve made the same mistake myself. But it’s hurting your friends, it’s hurting you, and it’s hurting the Internet. You need to stop.
You need to stop automatically dumping your feeds from one account into another.
Look, I know it’s tempting. New service, not sure how you’ll keep up with the ever demanding maw and there’s the “import your content” button, right there in the sign-up process. A quick trip through a login screen or an OAuth link and there you are: All your stuff automatically aggregated into a new one-stop-shop of the genius things that pop out of your head.
No muss, no fuss, right?
This is an illusory solution. It’s a false idol. It’s contributing to noise pollution on the Internet and the only people it helps are company execs who want to make spurious claims about “user engagement”. It’s diminishing the quality of your output and of others’ experiences.
You need to unlink your feeds and put a tiny bit more effort into using each service for what it is.
