I've just been hit by this from two IPs.
There is relevance in the visit - I know this client has links in a wordpress blog - and would like to help if these can be guaranteed genuine bots.
First one:
IP: 74.200.245.nnn (VirtaCore servers)
rDNS: None
UA: WordPress/MU; [
[RelevantWPsection].wordpress.com...]
Hits: 18 to same 403'd page
Second one (with more authority):
IP: 66.135.48.nnn (ServerBeach)
rDNS: web6.admin.sat.wordpress.com
UA: WordPress/MU; [
[RelevantWPsection].wordpress.com...]
Hits: 18 to same 403'd page
Possibly one is for link-testing or text and the other for images or something similar?
I do wish companies would identify their bots properly! And provide a bot identity page!
