Since the script in the last thread didn't work, here's a fixed version
Tired of being anonymous? Wanna be like your favourite /bant/ oldfig?
1) get Tampermonkey/Greasemonkey/Violentmonkey or other extensions who run userscripts for your browser.
2) once installed, click add/create new script
3) copy and paste the code found in https://pastebin.com/qT70NH1b
4) save and refresh /bant/ and you should have a flag option at the bottom of your 4chan page
5) set your flags and you're done
and yes it's 100% malware
