There is a site called gnaa.world run by "GNAA International". On the releases page is a long list of ongoing trolling operations carried out since 2020. They say they've done things like invade Roblox games, leak government data, trolled ISIS, closed forums, and a whole lot of other campains and exploits. They have a github where they post exploits and scripts used during trolling, and they recruit members through discord (discord.gg/gnaa). The site doesn't seem to have a last measure page so it's safe to browse.
Pmb1226 Interesting discovery, I wonder why they made it yellow.
