BLEXBot

BLEXBot is the tool or developer fetch run by WebMeUp: WebMeUp link index. Its operator publishes no IP ranges or DNS names for it, so a request carrying this name cannot be verified. Treat the name in a log line as a claim.

Add a group that names it: "User-agent: BLEXBot" followed by "Disallow: /". A crawler follows only the most specific group that names it, so once a group names BLEXBot, rules under "User-agent: *" no longer apply to it; repeat in that group any Disallow lines you still want.

What blocking it changes

No. It is a third-party tool's crawler. Blocking it changes what that tool knows about your site, not anyone's AI answers.
