The attack on the Capitol sparked a tense debate among online extremism researchers about crowdsourced efforts to identify the rioters and “ethical doxxing”
Joan Donovan has a panic button in her office, just in case one of the online extremists she spends her days fighting tries to fight back.

Joe Patrice / @josephpatrice : I feel like we need a different word than “doxxing” here. It may be functionally the same process, but posting private information because you don't like someone is a lot different than aiding in an ongoing criminal investigation and probably should have its own word. https://twitter.com/... Issie Lapowsky / @issielapowsky : NEW: Public, crowdsourced efforts to identify the Capitol rioters on Twitter are dividing online extremism researchers. The work is urgent. But also dangerous. What's the right way to out an insurrectionist online? https://www.protocol.com/... Joan Donovan, PhD / @bostonjoan : Just to be clear, I do believe the reason why we are in this situation is because the DC law enforcement, FBI, and DHS failed the country on Jan 6th. That is driving many researchers and activists to work on piecing this all together. Many fear that will happen again. https://twitter.com/... Melissa Murray / @profmmurray : The social media version of The Lysistrata🤣🤣 🤣 https://twitter.com/... Emily Guskin / @emgusk : “After swiping right in hopes she could get more information out of him, she said he responded that he did visit the Capitol and sent more pictures as proof. She later contacted the FBI tip line.” @drewharwell @lisabonos @craigtimberg https://www.washingtonpost.com/ ... Hussein Kanji / @hkanji : The uprising has sparked a tense debate about the right way to stitch together the digital scraps of someone's life to publicly accuse them of committing a crime https://www.protocol.com/... David Clinch / @davidclinchnews : It is important for professional/experienced researchers to create systems where tips can be sent offline or privately so the names of innocent people are not circulated online. Amateurs need to be very careful and platforms should be prepared to apply rules against doxxing. https://twitter.com/... @profcarroll : I think there's another undercurrent here at play as well though: That we don't trust law enforcement to do the work. https://twitter.com/... Issie Lapowsky / @issielapowsky : “I have this overarching thesis that the internet turns us all into cops. These are technologies of surveillance, and so use of them by the public to turn crowds into cops seems to me to be a very dangerous impulse.” - @BostonJoan https://www.protocol.com/... @hypervisible : “These are technologies of surveillance, and so use of them by the public to turn crowds into cops seems to me to be a very dangerous impulse.” https://www.protocol.com/...
Context & Ripple Effects
The debate sits in a longer arc in which online harassment and conspiracy communities were already crossing into offline harm. After the Capitol attack, platforms were purging harmful material while police sought to preserve evidence, making the boundary between public investigation and personal exposure unusually consequential.
First-order effects
- Extremism researchers are split over crowdsourced identification of alleged rioters, while Joan Donovan and other researchers face heightened personal-retaliation risks.
- Researchers are urging private, offline channels for tips and asking social platforms to enforce their existing anti-doxxing rules against public identification campaigns.
Second-order effects
- The FBI and other law-enforcement agencies face pressure to distinguish vetted evidence from crowdsourced claims as they identify suspects; later reporting documented the FBI's use of license-plate readers and facial recognition in its identification effort.
- Platforms' post-riot content removals become harder to separate from evidence preservation when posts can serve both as investigative leads and as material for harassment.
Third-order effects
- If public identification becomes a routine response to political violence, platforms and investigators will need clearer permission boundaries for public data, private identities, and the handoff of tips to authorities.
- The pattern shifts trust-and-safety work toward formal researcher and law-enforcement reporting channels rather than ad hoc public campaigns, with enforcement against doxxing as the limiting rule.
The trend: Political-violence investigations are exposing a growing governance divide between open-source accountability work and platforms' duty to protect people from targeted exposure.
