The ethics, and ethical governance, of online research have been much debated, and a number of professional organizations have promulgated guidelines for researchers considering conducting their research online. Although the datasets and tools that we provided are under either Creative Common or Open Access licenses, we encourage you to review potential ethical issues per project and do not release individual users' information without consents or anonymization. You can check our Resources
page for ethics discussion and feel free to use our workshop sessions to address your concerns on ethics. Also, you can consult IRB at your institute.
