[ExI] Invitation to connect on LinkedIn

[David Lubkin]

I find LinkedIn very useful but the "feature" that these sites have of
letting you blast an invite to everyone in your address book is
obnoxious. You'd *think* anyone you knew was smart enough to
know better.

List owners -- The first time I got a LinkedIn invite sent to a list
I run, I added a spam filter to reject them. It's trivial in Mailman --
just match on the header pattern

X-LinkedIn.*: .*
