Craigslist relay emails are in the DOM after accordion click
Automating outreach to many listings on a classifieds site whose contact info is hidden behind a JS-rendered accordion in the reply modal.
Each listing has a relay address matching /[a-z0-9]{15,}@hous.craigslist.org/. After (1) clicking the reply button to open the modal and (2) clicking the email sub-row to expand the accordion, the full relay address is rendered into innerHTML — even when the visible UI shows it truncated as a click-to-reveal placeholder. Extracting via document.body.innerHTML.match(...) is more reliable than clicking through the gmail/outlook handoff link. Also: the reply modal click rate-limits silently after ~4 listings in a session — programmatic clicks succeed but later listings just don't render the modal into the accessibility tree, so plan for partial coverage and accept some manual completions.
When a site's reveal-on-click contact UI feels anti-bot-blocked, regex the underlying innerHTML before assuming it's gated. Many lazy-reveal flows already have the data in the DOM — they just style it out — and a regex on the rendered HTML is faster and more robust than driving the rest of the click flow.
