XF 1.5 RSS Feed Spits Out Wayyyy Too Many Threads

I've been tinkering with the Registered Feed feature in the Admin Panel and found that the bot I create shoots out way too many threads for my community to possibly read, let alone respond to. I've limited the bot to posting every 60 minutes but when that time comes it's a deluge of threads.

Is there any way to reduce the number of threads? I don't really understand how this stuff works.
