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 various types of data including past and current account creation information and data associated with the account creation request such as IP address, username, password, cookie, and response time. Based on the analysis result, the server assigns a spam score to the account creation request 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.
