Claim 9:
10. A non-transitory computer-readable storage medium having program code that is executable by a processor device to cause a computing device to perform operations, the operations comprising:
receiving a risk assessment query that identifies an email address;
determining a plurality of features for the email address, wherein determining the plurality of features comprises determining a feature based on characters contained in the email address;
for each feature of the plurality of features, determining an expected safe value for the feature by calculating a median value of the feature for a set of legitimate historical email addresses, wherein calculating the median value of the feature comprises determining a weight for each legitimate historical email address of the set of legitimate historical email addresses based on a number of interactions of the legitimate historical email address with a risk assessment computing system;
for each feature of the plurality of features, calculating an illegitimacy score by calculating a deviation of the feature from the expected safe value for the feature;
aggregating the illegitimacy scores of the plurality of features into an aggregated illegitimacy score; and
transmitting a legitimacy risk value indicating the aggregated illegitimacy score to a remote computing system for use in controlling access of a computing device associated with the email address to one or more interactive computing environments.
