May it happen that CloudFlare stops sending their call invitations to me. I have an account at them which has shared access to company domains, because sometimes I was needed to assist with them. CloudFlare reps repeatedly e-mail me to schedule a call, even after I replied to them and told that I am not a person directly responsible for our domains and asked to stop mailing me. Whoever was their rep at that time, answered that they will stop. Some time passed, and they started e-mailing again. Eventually I started putting their e-mails to spam folder.
