Before deleting my account, I unsubscribed from several groups. Yet two weeks later I was still getting daily updates from the unsubscribed groups. Also, even though I had unsubscribed and they were not on my group list, they still showed up on my public profile. After two support tickets, the emails stopped.

Then I decided that LinkedIn was useless to me so I deleted my account. For two weeks, I still continued to get daily email updates even though I no longer had an account. After another support ticket, the emails stopped.
