You can be a member of (and be invited to) multiple teams on FraudFindr and access them using the same email address. When you login to your account, you’ll be prompted to select the team you’d like to access. You can also switch teams at any time by clicking Switch Teams button in the top right of your screen.

However, you cannot sign up for multiple new team accounts using the same email. Once you've signed up for a team account with your email, you can only be invited to new teams using that same email.
