Shutting down our preprint bots | Feb 21, 2023 | Liberate Science

"We started running Twitter bots in 2017, when Liberate Science was only a side project. First we launched the PsyArxiv bot. Later, we launched bots for the MetaArxiv (2020) and EdArxiv (2021) preprint servers. Six years in, we are shutting down these Twitter bots. You may have already noticed they are no longer posting any new preprints since February 13th (previously 9th). There are several things that motivate us to stop the preprint bots’ operations. It includes the exodus from Twitter overall; it includes the recent announcement that Twitter API access is no longer free. It includes that the community has taken it upon itself to offer replacement bots on Mastodon.   We offered preprint bots for free all these years, but that does not mean it was free to run this. We had to run a custom RSS feed service (based on Jeff Spies’ osfpreprints-feed; run on Glitch for $99/year). Automating a bot is free and easy if there is relatively little volume. Especially for PsyArxiv, the amount of preprints grew so rapidly that we had to upgrade our automation and costs went up to ~$600 per year (using Zapier). This is also why the 1,500 free post limit proves too uncertain in the long run...."
