What does this mean?

cosmorph.com provides temporary, disposable email addresses that allow users to receive emails without revealing their real identity. These addresses are typically short-lived and self-destruct after a set period.

Users of disposable email services can sign up for your product, abuse free tiers, create multiple accounts, and disappear without a trace. This leads to inflated user counts, wasted resources, and increased fraud risk.

With a severity rating of 3/5, cosmorph.com represents a moderate risk. We recommend flagging or blocking signups from this domain depending on your use case.
