Question 1

Why is it harder for researchers to study social media now?

Accepted Answer

Because platforms have **restricted or withdrawn the access** that independent research depended on — and this happened while the questions researchers are asked to answer became more consequential.

**What researchers previously had.** Application programming interfaces allowing systematic collection of public posts, network structures and engagement data at scale. This underpinned a substantial body of work on misinformation, polarisation, harassment, advertising transparency and public health communication.

**What changed:**

**API access was restricted or priced out of reach.** Several platforms introduced charges at levels far beyond academic budgets, or removed free research tiers entirely, and the change was frequently made with little notice.

**Research tools were shut down**, including transparency tools that had been widely relied upon.

**Accounts and projects were restricted**, including cases where researchers studying advertising or misinformation had access withdrawn — which drew significant criticism, since studying a platform is not the same as violating its terms.

**Terms of service prohibit automated collection**, so scraping carries legal and contractual risk even for clearly public data.

**Conversation moved to private spaces** — messaging apps and closed groups — that cannot be studied by observation at all, regardless of permission.

**Why platforms give for the restrictions:** privacy and data protection obligations, commercial value of the data, prevention of misuse, and infrastructure cost. **Each has some validity**, and the privacy argument in particular is genuine and not merely pretextual.

**Why the consequences are serious:**

**Independent verification of platform claims becomes impossible.** Only the platform can measure what happens on it, so its own reporting cannot be checked.

**Research lags reality**, and studies are increasingly based on older data or on the platforms that still permit access — which biases the literature toward whichever platform is most open rather than most important.

**Policy is made without evidence**, since regulators rely on research that can no longer be conducted.

**What is being attempted:** regulatory data access provisions, notably under the EU Digital Services Act, which obliges very large platforms to provide vetted researchers with data; independent data donation studies, where users voluntarily contribute their own data; and archival collaborations.

**Implementation has been slow and contested.**

Question 2

Why do people use social platforms as search engines now?

Accepted Answer

Because for a growing set of queries they answer the question better — and the shift is significant enough that search companies have publicly acknowledged it and redesigned results in response. What

Question 3

What is social commerce, and why are platforms pushing it so hard?

Accepted Answer

Buying and selling inside a social app rather than clicking through to a retailer's website — and platforms are pushing it because it solves their two biggest commercial problems at once. Why

Question 4

What does the evidence actually say about social media and mental health?

Accepted Answer

Genuinely contested, and both confident positions — that it is a public health catastrophe and that it is harmless moral panic — go beyond what the research supports. What is reasonably well

Question 5

How are political ads regulated on social platforms?

Accepted Answer

Inconsistently — through a patchwork of platform policies and national law that varies enormously by country, and in many places the rules governing political advertising online are considerably

Question 6

Why have online conversations moved to group chats and DMs?

Accepted Answer

Because the public feed became a bad place to talk — and the shift toward private and semi-private spaces is one of the most significant changes in how people actually use the internet, even though

Question 7

Why do so many sites close their comment sections?

Accepted Answer

Because the cost of running them honestly exceeds the value they produce for most publishers — a calculation that has shifted steadily as moderation costs rose and the traffic benefit fell. The
