Most cryptos are not anonymous. Pseudonymous is the word. If an address gets linked to any of your identities, everybody can see all your balances and all your transactions. And track them.
This page is like a search engine. Search for a Reddit user and see if they have any crypto address linked to their account.
Support for other social media platforms, such as Youtube and Twitter are on the roadmap.
