Abstract: Automatically fading online user content may include receiving digital content from a first user, the digital content associated with a first user-defined fading time indication; posting the digital content at a first time; associating, using the one or more computing devices, the first user-defined fading time indication with the digital content; receiving, at a second time, from a second user, a request to view the digital content, the second time being after the first time and the second user being distinct from the first user; determining the availability of the digital content based at least in part on the difference between the second time and the first time and the first user-defined fading time indication; and when the determined availability includes availability of one or more aspects of the digital content to the second user, providing for display to the second user the available one or more aspects.

Abstract: A computer-implemented method, including identifying user subscriptions that meet at least one criterion of a plurality of criteria for detecting subscriptions that are no longer active, classifying the user subscriptions into a first group and a second group, where user subscriptions in the first group have at least one context factor associated with the at least one criterion, matching the user subscriptions of the second group with data of unavailable users to produce a third group of user subscriptions, where the user subscriptions of the third group are successfully matched with some of the data of unavailable users.

Abstract: Systems and methods for detecting real names in different languages are described, including receiving a candidate name; determining a human language of the candidate name; disassembling a structure of the candidate name by applying a rule base for at least one of a character set, a meaning, and a format of the candidate name, wherein the rule base is unique to the determined human language; verifying at least a part of the disassembled structure of the candidate name with respect to actual real name information to generate a degree of confidence that the candidate name is the an actual real name; and performing an action based on the generated degree of confidence that the candidate name is the actual real name.
