I think the problem is more the fact that people like to throw around the word "abuse" with nothing to actually back it. I've seen quite a few times where a staff member will be doing their job and a person calls abuse on it.
"I got muted for micspamming after being given a ton of warning beforehand? WHAT IS THIS ABUSE?"
Obviously, if legitimate abuse is actually taking place, then I strongly suggest the player gather evidence and direct them to the appropriate place on how to create/creating an abuse report.
I believe we have a little ad that pops up in chat that says something along the lines of that, but I don't fully recall. If not, we could always add it.
Or potentially add a section to the MotD under the rules that says something like: "Think a staff member is abusing? Gather evidence and make a report here!"
Then add a link to the "creating a report" thread and a "What constitutes as abuse?" link with the little blurb @mrnutty12 posted.
