There are two separate problems. The basic issue seems to be that linkedin lets users upload address books and then send invitation-spam to all of them. When those addresses are individuals, that's one thing. When those addresses are lists, the problem is far worse. I've explained this to ab...@linkedin.com, and they seem not to care. One can observe that their rude behavior results in advertising. What's worse is that the mail is forged From: the user, not linkedin, so it passes "sender is a list member". So, there's one debate we could have about marking all linkedin invitations as spam; to me that's a marginal call. There's a second debate about removing any whitelist that claims they aren't spam, and I don't think there's any question that we should remove those whitelists. Then, it seems that what's spam to a user and what's spam to a mailinglist are different. I would guess that there is near 100% agreement that invitations to lists are always spam. I haven't written a rule, mostly because I don't run mailinglists that suffer from clueless linkedin users, but what I'd do is basically (manual config on the list, or match something, to say that it's a list) rule to match linked invitations if LIST and LINKEDIN, score 10 points. Optionally, unsubscribe the user. Alternatively, this could be built in to mailman. (Also, I forward every bogus invitation to ab...@linkedin.com, and this seems to result in them spending a few minutes giving me too-hard-to-believe-its-true claim it's not their fault.)
