Russian web brigades are groups of people who work together online to spread specific messages or propaganda. Imagine it like a group of friends who all want to convince others to believe the same thing they do. These groups are often paid by the Russian government or other organizations to spread their messages.
They might post comments on social media or news articles, write blog posts or articles, create memes, or even create fake accounts to spread their message more widely. They do this to try and influence people's opinions, especially when it comes to politics or current events.
It's important to be aware of these web brigades and their tactics so that we can think critically about the information we see online and not be swayed by propaganda.
