In all cases, the check for an existing matching contact uses the default "Individual Strict Duplicate Matching Rule" (match on email address). If you are concerned with existing contact data being over-written by anonymous visitors, you can modify this rule to make matches less likely (or even impossible). For example, if you NEVER want anonymous input to match (i.e. always create a new contact record) - edit that rule and set the 'weight threshold' higher than 10. You will then need to run Find Duplicates periodically using a different rule, and merge any duplicate records with their associated memberships, contributions, etc.
