You found us in your logs.

If you are a site owner who just saw StumbleWatch in an access log, this page is for you. It explains exactly what the crawler does, and how to stop it in one email.

user agent StumbleWatch/1.0 (+https://stumble.vimabrosta.com/bot)

01What it is doing

A customer asked Stumble to watch one of your public pages and tell them when something on it changes: a restock, a price drop, an appointment slot, a launch. The crawler fetches that page and nothing else.

behaviourguarantee
methodGET only. Never POST, never a form submission.
rateA minimum of 5 seconds between any two fetches to your host, across every customer.
backoffExponential on repeated 4xx or 5xx. Persistent failure marks the watch failing and it stops bothering you.
sizeAt most 2 MB per fetch. Non-text responses are discarded unread.
identityAlways the user agent above, with a link back to this page. Never spoofed.

02What it will never do

  • Log in, fill a form, or solve a CAPTCHA.
  • Purchase, book, reserve, or bid on anything.
  • Bypass a paywall, a rate limit, or any other access control, for any customer.
  • Store credentials. Targets behind authentication are refused at purchase time.
  • Crawl your site broadly. It fetches the exact URLs customers named, and no others.

03How to block it

Either of these works, and neither needs a reply from us:

  1. Return 403 or 429 to the user agent above. The crawler backs off automatically and the watch reports its failing health to the customer.
  2. Email contact@vimabrosta.com with your domain. We add it to the blocklist promptly, and every existing watch aimed at it stops.
No argument, no retention

We do not ask why, and we do not keep a copy of your pages beyond the short evidence excerpt a triggered watch shows its own customer. Blocks are honored on the domain, not negotiated per URL.
