Someone can help me creating a script like that?

There is a guy on this forum that created this code pretty quick but im not able to send any pm...
This is the thread where he posted that code using a browser script called tampermonkey:
blackhatworld.com/seo/new-xvideos-com-upload-page.1021313/


I need a similar code to add tags on a site called pornrabbit dot com
If someone can help me making this script or sending a pm to this guy i will send some bucks on paypal as a reward

Thanks everyone for the help guys
