Google TAG bulletins explained

What a bulletin is

Each bulletin opens with one line. The Q4 2025 bulletin says it includes coordinated influence operation campaigns terminated on Google platforms in Q4 2025 ¹. The Q3 2025 bulletin, published on 13 November 2025, uses the same wording for Q3 2025 ². Both are credited to Trust and Safety and the Threat Analysis Group ^1,2.

Entries are grouped by month. Each one starts with the action, for example a number of YouTube channels terminated, and then describes the campaign in a sentence ¹.

What each entry records

• Action: YouTube channels terminated, Blogger blogs, Ads accounts, or domains blocked from eligibility to appear on Google News surfaces and Discover ¹.
• Actor: a country such as Russia, Indonesia or Azerbaijan, or wording such as United Kingdom-based actors ¹.
• Links: some entries say the activity was linked to the Internet Research Agency or to a Russian consulting firm ¹.
• Languages: the languages the content used, for example Russian and Romanian ¹.
• Content: a short summary, for example content supportive of Russia and critical of Moldova ¹.
• Continuity: the larger PRC entries are described as part of an ongoing investigation and consistent with previous reports ¹.

Largest entries in Q3 and Q4 2025

The PRC entries and DRAGONBRIDGE

Google described DRAGONBRIDGE in January 2023 as a spammy influence network linked to China, which it says is known by the other name Spamouflage Dragon. It said it disrupted over 50,000 instances of its activity across YouTube, Blogger and AdSense in 2022 and had terminated over 100,000 of its accounts over the network's lifetime ³.

Google said most DRAGONBRIDGE channels had 0 subscribers when disrupted and over 80% of its videos had fewer than 100 views ³. The 2025 bulletins describe the PRC entries as content in Chinese and English about the PRC and US foreign affairs ^1,2.

How to read the counts

A bulletin entry counts accounts or channels, not people. In Q4 2025 single entries ranged from 1 YouTube channel to 6,280 ¹. The bulletins give no overall total, so any total is a reader's own sum ^1,2.

Channel terminations follow YouTube rules. YouTube's spam policy covers coordinated networks of channels and says it may terminate a channel or account ⁵. Domain blocks relate to Google News surfaces, where Google says sites with repeated or egregious violations may no longer be eligible to appear ⁶. Google's threat team shares findings with other companies. Meta said Google Threat Intelligence Group shared information that helped start one Iran investigation in 2025 ⁴.
