Usernames
Any verified or guessed usernames can be researched and verified if possible on social media sites.
Searching through forums, boards or messengers can also reveal a lot about someone’s online persona and activities. Usernames can be used as keywords to search for information on these types of platforms and can be an excellent way to find more relevant data. Using search operators to fine tune your queries on Google, DuckDuckGo, etc. can also provide better results.
