[Just in case -- This is titled this "C4PC" but post Preview shows "C4pc".]
search2.cloud4search.com
C4PC UserAgent/0.7
robots.txt? Yes BUT...
First request to robots.txt used "-" as the UA and was blocked (no UA; hmm). Second hit to / used UA above also blocked (no Moz).
Search results full of hits from multi-numbered subdomains but WHO sez no site, no profile; just registered in France via OVH SAS. The owner, CLOUD4PC, matches the UA name (C4PC), and cloud4pc.com -- also no site, no profile, but "coming soon" -- is also OVH SAS in France, long a source of troublesome UAs and Hostnames.
FWIW, I've been redirecting "cloud" because of junk from multiple .static.cloud-ips.com accounts, etc. Not a single real user yet.
