Gatekeeping (communication) Gatekeeping is the process through which information is filtered for dissemination, whether for publication, broadcasting, the Internet, or some other mode of communication.
That is certainly one use of the word gatekeeping. Another common use of the word is:
“when someone takes it upon themselves to decide who does or does not have access or rights to a community or identity”.
Linking to upstream source instead of copying answer that will be outdated is neither gatekeeping nor “RTFM toxicity”
