I just finished a conversation with my boss' boss, telling me (as nice as he can) to make all my facebook posts both future and past as hidden as possible.
When I asked why, he made it clear. People are having their lives ruined by posting a maga hat and he was looking out for my best interests.
I work for a fortune 500 company, multi-national and my position is pretty damned important (only about 10 people are in my position in a huge multi-national company) and my boss' boss is warning me against having my whole life destroyed.
I can't tell if I should be mad, sad, or terrified.
They are hunting for you. If your company can be influenced to lean on other companies, if stock price can be hurt, if someone is willing to trade your 'scalp' to avoid the threat of the leftists, take it seriously. One of ten? There's 9 to pick up the slack.
Identify your public and semi-private social media accounts.
Nothing is 100% private if you are a publicly valuable target. It just takes a tech-insider to leak. For the rest, you have to think 'which friends are semi-trustworthy'?
Quietly - scrub any 'default to public' accounts like Twitter. Remove all references to employers or business.
Get a Protonmail account and move any social media accounts profiles to it.
Never use an email with your real name on anything connected online unless you run it like a pure-public account sanitized for universal acceptance.
If you're still on FB (semi-private social media), cull any friends lists of anyone even marginally sympathetic to critical-race-theory. Remove them or use 'restricted' groups that keep them from content.
Note that all profile and banner photos are usually 'public' by default. Delete them or mark them friends only. You only need one profile photo and one banner public. Change settings to hide friends, books, other interests.
You can start a new FB account and scrap the old one. Do not announce it to friends, just print your friends list and re-friend only those you trust. If you warn everyone, some may take screen shots of content.
Off the top of my head, not that I've thought about it.
