I keep a list of services I closed or asked for my account to be removed and forgot. Today you even often have to make an account to take a look at a tech demo, because the author tries to avoid abuse of their AI service key they used for such demo.
After about two years many of these services start sending me messages again. Sometimes it turns out that the account is active again.
Recently a recruiter send me an email with a standard cold call: "I have a position that will be a perfect fit for you". I asked where she got my contact and how's that position be a perfect fit, trying to get a feel what she actually knows about me. She said she got the my profile from LinkedIn. When I asked her to post me a link to my profile it turned out the profile was closed. Somehow LI kept the profile and shared my details when she used some recruiter features. ;)
