Spam iPhoto invites

[Rilot]

Getting a lot of these now. Directly to my apple ID. They show up in iPhoto as invites to join a shared iPhoto album.
Unfortunately I don't see any way to either block them or to delete them without declining them (declining sends a message to the sender and thus invites more spam as it shows the account is active) and it's starting to become quite irritating.

Any ideas?

Well, the only solution I found to the iCloud photo sharing invites is to turn the feature off.
Settings -> Camera & Photos -> Turn off iCloud photo sharing.
