Just today and yesterday I saw that my calendar has some weird Chinese invitations that were added. I noticed that they were coming from my iCloud in my "Work" section. I deleted them yesterday, but they reappeared again today. The invitations seems to add one to almost every single day on my calendar. Does anyone know how this is happening and any way to permanently get rid of them from getting re added? I don't have anyone on my contacts that that have this info.
