I have a couple of domains that are using the free CloudFlare SSL cert configured as Flexible SSL. Connections to the domain is fine. However when I signed up for a free account on SSLmate.com and used their fre CertSpotter option all of the domains returned 72 unexpired certs that were issued for the domains in question as well as a whole bunch of other domains that are not mine. The Issue date rangers from 2018-05-05 with an expiration of 2018-11-11 to issuance date of 2017-11-04 with expiration date of 2018-05-13. All of these certs were issued via Comodo.
I can see using wildcard certs for a bunch of domains that are using Cloudflare but why are there so many apparent valid SSL certs according to SSLmate.com and their CertSpotter?
