I am new to Tor. I'm not using it for anything illegal or suspicious, I just want to protect my privacy.

I accidentally logged into YouTube, Facebook and Twitter via Tor yesterday. Have I permanently blown my cover? Or just for yesterday's browsing? Do I need to buy a new computer or clean install my OS? I'm moving across the country (US) in a couple weeks - does that help my case at all?

Also worth mentioning: The accounts I logged into were WORK accounts. I'm a comedian so I use social media to connect with fans. These channels are in my name but I don't use them for personal/private communication. Also, I'm not the only one with access to these accounts, so is it "possible" that someone who works for me logged into the accounts (manager, agent, assistant)?

To sum up: How big of a mistake was this? And if it was a big one, are there steps I can take to reverse it?
