It cannot be done by name. Squarespace’s “Block known artificial intelligence crawlers” checkbox covers a fixed list that does not include Poseidon Research Crawler, and robots.txt cannot be edited on Squarespace.
You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/poseidon-research-crawler/squarespace with the UI removed — the content only. A browser asking for the same address gets the full designed page.
Poseidon Research Crawler is a crawler run by Poseidon Research. It reads pages ahead of time, to train a model or to build an index.
Squarespace writes robots.txt itself and does not let it be edited. The one control is a checkbox that adds a fixed list of AI crawlers to it.
Poseidon Research Crawler cannot be refused by name on Squarespace. The names its checkbox does cover are: AI2Bot, Ai2Bot-Dolma, aiHitBot, Amazonbot, anthropic-ai, Applebot-Extended, Bytespider, CCBot, ClaudeBot, cohere-ai, cohere-training-data-crawler, DuckAssistBot, FacebookBot, Google-Extended, GoogleOther, GoogleOther-Image, GoogleOther-Video, GPTBot, img2dataset, Meta-ExternalAgent, MyCentralAIScraperBot, omgili, omgilibot, Quora-Bot, TikTokSpider, YouBot.
Squarespace has no setting that refuses a request by its user agent. robots.txt is a request. A crawler that honours it stays out; nothing in the file stops one that does not. What is enforced is what the server or the edge in front of it refuses.
A 200 means the name is let through; a 403 means something in front of the page refuses it. This tests the name from your own address. A platform that checks a crawler’s address as well may treat the real Poseidon Research Crawler differently.
The request:
curl -I -A "Poseidon Research Crawler" https://your-site.example/

Nothing has to be done: no setting on Squarespace names Poseidon Research Crawler, so it follows the rules everyone follows.

No. Googlebot goes by its own name and follows its own rules; a group or a firewall rule for Poseidon Research Crawler does not apply to it.
Citable strips the UI from a website for AI agents and serves them only the content.
When an AI agent — ChatGPT, Claude, Perplexity or any of the 81 that Citable recognises — opens a page, Citable removes the theme, scripts, navigation and layout and serves only the content: the same facts, at the same URL, on the site's own domain. People and Google still get the full designed page.
