What it is

Not an operator: desktop crawling software that anybody can point at any site. The default user-agent identifies the tool, not who is running it, and the operator of the moment is whoever pressed start.

What blocking it costs you

You block a consultant auditing your own site as often as you block a stranger. Treat it as a rate-limit question, not a consent one — and note that the user-agent is configurable, so a block is advisory.
