My guess is that it's similar to the reason curl (and wget) sometimes get identified as malware by virus checkers.

Someone in US Immigration Googled 'curl' with your name and found a bunch of malware hits.

Certainly curl is used by lots of malware, and many a hacker probably use curl in their software.

I guess it's possible he was flagged by someone reviewing malware. Would malware creators give any credits?
