Many of the rebel's twitter & YouTube accounts are run by UK government

""The British government is waging information warfare in Syria by funding media operations for some rebel fighting groups," "The campaign aims to boost the reputation of what the government calls the “moderate armed opposition”, a complex and shifting alliance of armed factions." "Contractors hired by the Foreign Office but overseen by the Ministry of Defence (MoD) produce videos, photos, military reports, radio broadcasts, print products and social media posts branded with the logos of fighting groups, and effectively run a press office for opposition fighters. Materials are circulated in the Arabic broadcast media and posted online with no indication of British government involvement.""
