1/ Useful thread, including analysis by my colleague @brianfishman. There are clear parallels to lessons learned in IO. Not surprising, as IO and CT share key underpinnings: security challenges driven by determined and adaptable adversaries. https://twitter.com/AmarAmarasingam/status/1348147867739975681

2/ On the IO side, deplatforming has had significant impact on nation-state and sophisticated threat actors. For example, increased enforcement has helped drive Russian ops increasingly off-platform.

3/ Even recent IO campaigns, which tried to use major platforms to amplify their off-platform assets, have been caught sooner before they could build audiences. In other words, they've kept trying, but pushing them off platform has made them less and less effective.

4/ Deplatforming is a powerful tool that helps contain IO adversaries & hate groups. It's important to take it seriously, use it where warranted, be transparent about the basis for enforcement, & take into account the impact that it has, both on security & on speech more broadly.

5/ Thank you @AmarAmarasingam for this thread -- it's a good reminder that there are many opportunities for IO and CT to learn from each other, and to join forces as we see threat actors (particularly white supremacists) use deceptive tactics online to enable their offline goals.
