LinkedIn were sneaky comandeered ALL my contacts list with 'tick' I didn't see when join, then proceeded to email EVERYONE an invitation from me, some of the contacts in the list I wanted 'nothing to do with', inviting them to join linkedin, including a DECEASED PERSON. Complained, wanted proof of death, I only had email inviting me to her funeral, they refused withdrawal & all other unauthorized emails. Unscrupulous & unethical. Linkedin fined for hidden 'tick'. YAY. No resolve for me.
