Hello! Sorry for the inconvenience. It's unfortunate that users can't block entire instances in Lemmy currently but fanaticus does provide a service for those who want to keep up to date with their favorite sports team. This isn't a novel idea, we actually implemented the same bots we enjoyed on Reddit.
If you'd like to cut down on the noise on your own feed you have a couple of options: you can disable bots in your personal settings so you won't see any bot traffic or you can run a script I wrote that will add all of our game bots to your personal Blocklist.
Lmk if you want the script and I'll dig it up.
