Impersonation detection and abuse prevention machines

A non-transitory machine-readable medium comprising instructions which, when executed by one or more machines in a social networking service, cause the one or more machines to carry out operations comprising:

• receiving, at a batch server of the social networking service, a new registration or an update for an account, the account comprising a name and identity-related information;
• determining, at the batch server of the social networking service, that the name and the identity-related information of the account matches one or more other accounts of the social networking service;
• detecting, at the batch server, a suspicious behavior of the account;
• and
• limiting, in response to the suspicious behavior, access to the account unless or until an identity of a user of the account is verified;
• determining, at the batch server and after receiving the new registration or the update for the account, if the name and the identity-related information of the account correspond to a tier II identifier from a Tier II Identifier Data Repository, the Tier II Identifier Data Repository being coupled with the batch server;
• and
• in a case where the name and the identity-related information correspond to the tier II identifier:
• limiting access to the account unless or until an identity of a user of the account is verified.

A system comprising:

• a management server and a batch server, the management server operating in real-time, and the batch server operating via non-real-time batch processing, wherein the management server comprises a management server hardware processor and a management server memory, and wherein the batch server comprises a batch server hardware processor and a batch server memory;
• the management server or the batch server to receive a new registration or an update for an update for an account, the account comprising a name and identity-related information;
• the batch server to determine that the name and the identity-related information of the account matches one or more other accounts of a social networking service;
• the batch server to detect a suspicious behavior of the account;
• the batch server to limit, in response to the suspicious behavior, access to the account unless or until an identity of a user of the account is verified;
• wherein the batch server is further to:
• determine, at the batch server and after receiving the new registration or the update for the account, if the name and the identity-related information of the account correspond to a tier II identifier from a Tier II Identifier Data Repository, the Tier II Identifier Data Repository being coupled with the batch server;
• and
• in a case where the name and the identity-related information correspond to the tier II identifier:
• limit access to the account unless or until an identity of a user of the account is verified.

A method comprising:

• receiving, at a management server of a social networking service, a new registration or an update for an account, the account comprising a name and identity-related information;
• determining, at the management server and in real-time upon receiving the new registration or the update for the account, if the name and the identity-related information of the account correspond to a tier III identifier from a Tier III Identifier Data Repository, the Tier III Identifier Data Repository being coupled with the management server and a batch server, and
• in a case where the name and the identity-related information correspond to the tier III identifier:
• blocking access to the account unless an identity of a user of the account is verified.

A method comprising:

• receiving, at a batch server of a social networking service, a new registration or an update for an account, the account comprising a name and identity-related information;
• determining, at the batch server and after receiving the new registration or the update for the account, if the name and the identity-related information of the account correspond to a tier II identifier from a Tier II Identifier Data Repository, the Tier II Identifier Data Repository being coupled with the batch server;
• and
• in a case where the name and the identity-related information correspond to the tier II identifier:
• limiting access to the account unless or until an identity of a user of the account is verified.
