Hmmm. Within minutes of my posting an item to this list, I saw that lo.gmane.org was accessing my webserver:
lo.gmane.org(80.91.229.12) - - [03/Mar/2016:13:18:07 +0000] "GET / HTTP/1.1" 200 430
lo.gmane.org(80.91.229.12) - - [03/Mar/2016:13:18:07 +0000] "GET /favicon.ico HTTP/1.1" 404 310
lo.gmane.org(80.91.229.12) - - [03/Mar/2016:13:18:07 +0000] "GET /robots.txt HTTP/1.1" 200 27
Can't be a coincidence, I think.
Normal behaviour? New? Reasonable? I'm surprised, because it means gmane is guessing a url from an email address. At least it honours robots.
