Apple has issued a statement in response to a problem that many iCloud users — including members of our iLounge team — have experienced in recent weeks, with spam being sent via iCloud calendar invitations. Spammers have been exploiting the fact that iCloud calendar invitations are sent via a dedicated iCloud communications channel that, unlike email, doesn’t presently include any anti-spam filters. In a statement tweeted by Rene Ritchie, Apple apologized, noting that some users are experiencing the problem. The company is working to address it by identifying and blocking the culprits, and working to filter the invites themselves.
In the meantime, users can work around this problem by logging into their web-based iCloud account online at iCloud.com, going to the Advanced tab in Calendar preferences, and opting to receive event invitations as email messages rather than in-app notifications, where email-based anti-spam filters will likely have better success at catching the bogus calendar invites.
