It is super important, now more than ever, to be safe online and to be a good digital citizen. Remember there is a huge difference between personal and private information.
Here is a link to a document about keeping yourself safe on Instagram. The advice is aimed for LGBTQ+ youth on Instagram, but the advice is good for anyone on any social media platform.
And remember, be an upstander, not a bystander. If you see or know of someone being bullied online, stand up for them. Support the victim. And tell a trusted adult.
Be safe, everyone, and make good choices.
