Similar thing here, every couple months for a year, original invitation over two years ago. I haven’t personally been all that bothered by it honestly - it seemed pretty likely that my friend is not sending a new invitation every couple months like clockwork, and presumably I can stop it by clicking once on unsubscribe. But probably it would be better to be explicit that it is not a new invitation.
