User-Agent

Incertae sedis

What is User-Agent?

A self-declared bot that is not in the keepers' catalogue yet. It calls itself “User-Agent”. It is operated by Unknown and identifies itself as User-Agent.

Temperament: unknown. Recently arrived. The keepers are still taking notes.

§ I.

Identification

Its full user-agent string, exactly as it arrives at the gate:

User-Agent
$ User-Agent:Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/140.0.0.0 Safari/537.36 Edg/140.0.0.0; 360Spider

There is no operator to verify against. This name is what software calls itself when nobody gave it one.

IdentityNothing to check against

No operator stands behind this name, so there is nothing to check its visits against.

§ II.

How to block User-Agent

Add these two lines to the robots.txt file at the root of your site. Well-behaved crawlers read it before they crawl, so the change applies from User-Agent's next visit. Nothing else on your site needs to change.

robots.txt
# Block User-Agent from the whole site
User-agent: User-Agent
Disallow: /

Or let it visit but keep it away from part of the site:

# Let it in, but keep it out of one room
User-agent: User-Agent
Allow: /
Disallow: /members/

Where it comes from

Scripts and scanners run from wherever their owners rent a server. These are the networks behind the visits on file:

Networks · 1 on file, last 30 days
China Telecom (Group) AS4811100%
Countries

Networks and countries come from the visitor's IP address, looked up in a local copy of the DB-IP database. The addresses themselves are never stored.

Questions site owners ask

Does User-Agent respect robots.txt?

Yes. In 21 requests observed here it has read robots.txt and never fetched a disallowed page.

Will blocking User-Agent hurt my search rankings?

No. Nothing respectable will miss it.

How often does User-Agent visit?

Here, about 1 requests a day over the last week. Visits to your site depend on its size, how often it changes, and how many links point to it.
