That’s just how federation works. You’ve federated with an instance/user so now your self hosted instance will be updated.
Is there a reason you’re concerned about the requests? The payloads should be relatively small, and unless you’re running on some really old hardware, one request a second with a small payload should not have any noticeable impact.
Yeah I’m always running my self-hosted projects on the smallest and cheapest VPC I can find. But apart from flooding my logs I haven’t noticed anything else being too much affected by this. I’m currently improving the observability of my system though, so who knows.
I was just a little concerned. Thanks for answering!
