Unable to delete my account
The connection requests that I get from LinkedIn are from (a) people I've never heard of, (b) tradesmen that I contacted but who never actually came to see the job and (c) people with the same name as someone that (let's say) my partner doesn't know that I know. In the last case, Apple must have sold LinkedIn my name and email address and the name but not the address of the person in question.
The link for deleting your LinkedIn account is not hard to find. However, when I hit the final "close account" button, nothing happens. I send a "feedback" message saying this and am told to go to the same page. I try to reply by email saying that it doesn't work and I get a delivery report saying "mailbox over quota".
