All is quiet on the security front as it relates to CatholicMatch. We have regular PCI Compliance scans, and we have had no indication of any kind of security issue.
A person who gave their email out to you has most likely given it out to other people, and giving out your email address to someone before you are comfortable with them and have established a repoir is inadvisable. Please make use of the anonymity that communicating through CatholicMatch provides. And remember: any email address - even a newly created one - can receive spam. Treat all messages from unexpected sources as untrustworthy.
