The biggest complaint I hear about LinkedIn is the amount of email the company sends users (not mail generated by other users, but mail generated by LinkedIn itself). It also seems to rather consistently ask to access your email contacts ("who do you know on LinkedIn?").

They also maintain shadow profiles of people who don't use linkedin by scraping their users address books.

It's a really scummy company.

A really good way to deal with this is just mark all those mails as SPAM. Let them eat the negative SPAM feedback until all their mails end up in the trash.
