Bots and fake accounts: what the statistics count

An account estimate, an enforcement count and a bot rate answer different questions.

These disclosures do not provide a universal bot percentage—or a U.S. bot rate. A platform can estimate account categories within an active audience or count accounts it removed over a year. Those figures have different denominators and periods.

For example, Meta estimated that approximately 4% of worldwide Facebook MAUs were false accounts in the fourth quarter of 2023. Its category includes misclassified profiles as well as violating accounts; it is not a bots-only measure. Meta 2023 Form 10-K, limitations of key metrics.

Meta describes internal review of a limited account sample and significant judgment. Sample size, standard errors and confidence intervals are not specified in these selected disclosures. Whole-percent approximation must not be treated as exact precision.

Duplicate account
An additional account a person maintains alongside a principal account. That definition alone does not establish automation, impersonation or malicious intent.
User-misclassified account
A personal profile used for a business, organization or nonhuman entity, such as a pet, instead of the source’s intended Page format.
Violating account
A profile Meta believes is intended for uses that violate its terms, with bots and spam given as examples. This is one part of the broader false-account category.

Definitions paraphrased from Meta’s account-metric limitations. They are the definitions in this historical disclosure, not universal categories for every platform.

Do not add 10% and 4% and call the result a “fake-user rate,” or subtract both from 100% to estimate real people. The source does not establish the mutually exclusive, exhaustive classification that calculation would require. Accounts are also not the same thing as distinct people.

A removal count measures recorded enforcement

In a separate disclosure, Bluesky reported removing 3,619 accounts for involvement in suspected influence operations during 2025. This is a service reporting count; no U.S.-only filter is specified. Bluesky 2025 Transparency Report, Influence Operations.

The count covers accounts identified through manual investigations and automated systems for suspected influence-operation activity. Bluesky cautions that additional affected accounts may have been removed through other enforcement processes without being specifically attributed to influence operations. The source’s “suspected” qualification matters.

Source: Influence Operations section. Accounts, not reports, posts, identified people or proven bots. No sampling interval supplied; this is an operational count with detection and attribution limits.

This figure does not say how many such accounts remained on the service, how many distinct people operated them, or what share of all accounts were bots. Dividing it by an unrelated year-end registered-account or active-user count would not repair those missing definitions. More removals can reflect different detection or enforcement activity; the count alone does not establish a change in underlying prevalence.

Facebook’s approximate MAU shares and Bluesky’s annual removals belong in separate panels. They cannot rank the platforms by bot prevalence or safety.

Methods, dates and reuse

Facebook’s active-user base and estimate limits

A Facebook MAU in the cited filing is a registered and logged-in user who visited Facebook or used Messenger while also registered with Facebook during the preceding 30 days. The account-quality percentages are described as fourth-quarter estimates; we do not relabel them as an exact December 31 census.

Meta uses internal signals and reviewer judgment, and warns that signal access, methodologies and product changes can affect estimates. Actual duplicate and false-account numbers may differ substantially. No subgroup, U.S.-only rate, trend, confidence interval or numerical “correction” to its MAU total is calculated here.
