Issue surfaced before solving the above ticket, and persists even with a Captcha in place and up-to-date MW version.
This creates an overload for the Wikibase admin to manage the legitimate account requests of potential contributors to the Wikibase.

AC:
- Stress test the Captcha
- Add timeframe when the issues occur to check if people are actually solving the Captcha when these accounts are created, if it's not solved, they're bypassing it. Timeframe: May 5th, all day, furry.wikibase.cloud (see comment: "There are ~50 spam requests in the last day. Many of them are marked as having confirmed email addresses. In total there were 1751 in the last month (showing as open requests), which suggests the rate has not changed recently.")
