Stop "X starred Y" from clogging my "All Activity" feed?

I have a few repositories that I like to monitor from the “All Activity” feed.
Unfortunately, a repository that I made a while ago (it’s not Watched, and it’s Archived) still often gets starred and forked, and its a little irritating seeing those events still appearing on my feed when I’ve very much moved on from that project.
Is there any way to prevent that type of activity form appearing on my “Main Activity” feed? Or is it just a behaviour I’ll have to live with?
