- Endorsements. They serve no purpose other than "look I am so cool" and for recruiter to find you by keywords that does not make much sense. Plus I have no interest in getting endorsed by my uncle for something he has no clue about.
- Groups: These end up being nothing but recruiter spam.
- Stop the spam of "Please join linkedin premium trial for 30 days". I get this email every other week. If I am interested, I would have joined by now. Don't you get it.
- And the classic one. It is ok for you to spam my gmail contacts but I cannot even send a group email to all my connections at once (you have a stupid cap)? One use case is that during the Christmas/new Year time, I like to send a note to all my contacts saying hi. Yes not very pesonalized but for me the whole point of linkedin is to stay in touch with my professional connections. Guess what ? You limit the number of connections I can send a note to in one message. really ?
