Yahoo blocks Trillian from its networks
Found on The Inquirer on Wednesday, 23 June 2004
Yahoo altered its instant messaging language to stop third-party programs, such as Trillian and the slightly-less-popular Miranda from working with Yahoo's service – Yahoo says the move is meant to prevent spamming on the network.
Trillian's often under flak from the major instant messaging groups – not too long ago, Microsoft blocked Trillian access to the MSN network, however Trillian got around that block.
On the Trillian forums, "Pneumatic" was quoted as saying: "This is a known issue and the developers are working on it. When an update is available we will post it in the announcements section." Considering Trillian's ability to get around blocks in the past, it looks like the Yahoo block may not be so successful after all.
Sure, banning other clients will eliminate spam. That's ridiculous. You could also say that blocking a special email client will stop spam. What they don't seem to know is that you can still analyze the protocol and write a program designed to spam. I doubt mass-messaging is done with Trillian.
