As @Socialphilosopher@lemm.ee said, you can block instances using this app but you cannot do it server sided. To do it from the app go to Setting> post list > filter > instance.
There are also controls there to hide NSFW if you'd like or filter posts by keyword or regex. It should be pretty powerful.
