Since many people can't access the post anyhow, the short version of 'why' is: instagram keeps trying to block bibliogram (we can't have nice things), the author is tired of working around it, the author is also tired of fighting on a second front against the bots that try to scrape bibliogram. The bots also try hard to circumvent blocks that the author needed to put in place, rather than spending the time learning how to run their own instance and going to town on that.<p>Of course, it's open source so it's not like it's "discontinued" in the same sense as if gmail were to be announced to be discontinued. The official server will even remain online, just with current limitations (like viewing profiles being blocked by facebook) not being fixed for the foreseeable future.
