Abstract
A computer implemented method for detecting and preventing spam account generation is disclosed. Upon receiving an account creation request from a client, the server analyzes the request and associates a spam score with the account creation request, based at least in part on a number of new account requests associated with the cookie received during a predefined time period, and compares the spam score with certain predefined thresholds. If the spam score is above a first threshold, the server may refuse the account creation request. If the spam score is within a certain range, the server may limit the access to the account associated with the account creation request. If the spam score is below a second threshold, the server may put no limit on access to (i.e., enable normal use of) the account.
