=== Blocking from Yahoo! and cooperation with Gaim ===
A few weeks after ''Trillian Pro 2.0'' was released, [[Yahoo!]] attempted to block Trillian from connecting to its service<ref>[http://news.cnet.com/2100-1032_3-5245821.htmll CNet article] on Yahoo blocking Trillian access{{dead link|date=September 2010}}</ref> in their "efforts to implement preventative measures to protect our users from potential spammers." A few patches were released by the Trillian developers, which resolved the issue.

The Trillian developers assisted its open-source cross-platform rival [[Pidgin (software)|Gaim]] in solving the Yahoo! connection issues. [[Sean Egan]], the developer of Gaim, posted in its site, "Our friends over at Cerulean Studios managed to break my speed record at cracking Yahoo! authentication schemes with an impressive feat of hackery. They sent it over and here it is in Gaim 0.70." It was later revealed that the developers were friends and had helped each other on past occasions.<ref>[https://archive.today/20070706050734/http://www.linux.com/feature/31728 Linux.com Gaims IM services play] on cooperation between Cerulean and Gaim</ref>

Meanwhile, as Microsoft forced its users to upgrade to MSN Messenger 5.0 for upgrades in their servers for security issues,<ref>[https://archive.today/20120713134549/http://news.com.com/2100-1032_3-5066412.html?tag=techdirt Microsoft upgrades to MSN Messenger 5.0]</ref> October 15, 2003 also would mark the deadline for Trillian support for MSN Messenger. However, it appeared that Cerulean Studios worked with [[Microsoft]]<ref>[http://forums.ceruleanstudios.com/showthread.php?t=41209?tag=Cerulean Studios released patch on forums before server changes happened in MSN Messenger] {{webarchive|url=https://web.archive.org/web/20160304035709/http://forums.ceruleanstudios.com/showthread.php?t=41209%3Ftag%3DCerulean |date=2016-03-04 }}</ref> to resolve the issue on August 2, 2003, long before the deadline.

On March 7, 2004, and June 23, 2004, Yahoo! changed its instant messaging language again to prevent third-party services, such as Trillian, from accessing its service. Like prior statements, the company said the block is meant as a pre-emptive measure against spammers.<ref>[https://www.cnet.com/tech/services-and-software/yahoo-to-trillian-talk-to-the-hand/ CNet article] on Yahoo!
