I just invoked my GDPR right to delete/close my account: https://www.linkedin.com/help/linkedin/answer/a1379064/ and got this result:

Your LinkedIn account is now closed. Although you no longer have access to it, it’ll take a few weeks for your public profile to disappear from search engines. Your data will be deleted as described in section 4.3 of our Privacy Policy

So at least this still works.

Could we please stop to pretend that US troops would help Europe if it was attacked by Putin? I mean Putin surely calculates that way and we know the US is currently our enemy, Trump said countless times that he doesn’t like the way we do things here in Europe. Better get rid of US influence entirely. It’s better to wake up now and have time to prepare instead of finding out that US won’t defend Europe in the middle of a future Russian invasion.

100% entirely incorrect. Data processing can happen without consent. Otherwise I could just tell my tax office to not store data about me and wouldn’t need to pay taxes. This is obviously not possible. In the end, art. 6 1. c) could justify such processing. Parental consent as described in art. 8 is only needed if Art. 6 1. a) were the sole justification.
