The popular IM from Yahoo is once again blocking other programs like Trillian, Kopete, etc... According to Yahoo "the block is meant as a pre-emptive measure against spammers from its Yahoo Messenger service."
Yahoo on Wednesday began blocking Cerulean Studios" Trillian software from communicating with its instant messaging service in its latest step to fence its popular client from third-party integrators. Beginning at about 6 p.m. Wednesday, Yahoo changed its instant messaging language to prevent third-party services, such as Trillian, from accessing its service. Like previous statements, the company said the block is meant as a pre-emptive measure against spammers from its Yahoo Messenger service.
"Spammers are being aided by entities that are abusing our systems, where they effortlessly gain knowledge of pathways and back-alley access to send spam," Yahoo spokeswoman Mary Osako said. A Trillian spokesperson did not immediately return an e-mail seeking comment. Trillian software essentially folds in multiple IM clients under one interface. Although IM services from Yahoo, America Online and MSN cannot directly communicate, Trillian allows a user to chat with their buddies on all three systems under a common look and feel.
