@dimuthudca @washingtonpost Thanks! It would mostly be on the platform. But, data journalism is something I'm passionate about, and perhaps a future direction

Happy to announce that I defended my dissertation on "Using Stylometry to Mitigate Abuse in Online Communities", advised by @ragreens. Thanks to everyone who helped me throughout the Ph.D. journey!

Is "InstaPy" an optimizer, an equalizer, or a step toward an AI arms race between platforms and users? https://t.co/PcxKS4QRnW
