I would like to propose renaming the csrf tag to cross-site-request-forgery.
a cross site request forgery attack causes a visitor of a malicious website to send a request to a legit website to which he is already logged in including the session cookie.
The tag was originally abbreviated to fit within the 25 character limit. Now that the maximum tag length has been increased to 35, I don't see any reason not to use the full name, while keeping the abbreviated name as a tag synonym.
