They have also made a controversial move to display advertisements in webmail despite users having to pay for the service (usually in paid web-apps, there is no advertising). BitTorrent traffic was restricted through bandwidth throttling using the SCE-2020, and in later years, the SCE-8000 from Cisco Systems Inc, which had caused complaints as users felt Rogers was overstepping their bounds as a service provider and despite Rogers advertising their service "for sharing large files and much more". Rogers had previously denied such allegations, despite widespread reports of the issue. Further controversy arose when in May 2007, Rogers began throttling all encrypted file transfers allegedly to combat BitTorrent traffic, but affecting all encrypted transfers regardless if they are BitTorrent traffic or not. In January 2011, the CRTC issued a letter to Rogers stating it was breaking CRTC policy by not "indicat[ing] that there are circumstances whereby the Rogers ITMP will also affect download speeds available to subscribers." Despite the letter from the CRTC, Rogers still had not updated their policy pages as of February 4, 2011, and continued throttling all non-whitelisted internet traffic (no longer just P2P) for up to 15 minutes after P2P had been disabled. Several games had been caught up in this more restrictive throttling as Rogers was incorrectly detecting them as P2P, and had also been slow to fix it despite offers of assistance from customers, and game manufacturers. On May 31, 2011, Rogers filed that they had resolved the World of Warcraft throttling, however they had only resolved it on their testing equipment, as users were still experiencing throttling. This resulted in the CRTC ordering testing done by Rogers, and the CRTC providing the complainant (Teresa Murphy) a redacted copy of the Rogers testing. On September 22, 2011, the CRTC released Telecom Information Bulletin CRTC 2011-609, which set out new steps for complaints, and allowed for the World of Warcraft complaint to be sent to the CRTC Enforcements division. While the World of Warcraft complaint was then closed as it was resolved, the creators of the WoW complaint created a new one, which was then sent to Enforcements division, who then began looking into Rogers' throttling practices, and found additional  non-compliance. After Bell announced they were ending throttling in December 2011, and the CRTC Enforcement division finding another violation of CRTC throttling policy in January 2012, Rogers announced on Feb 6, 2012 that they were ending throttling on their network by the end of 2012.
