On one hand I think we maybe shouldn't be too overly sensitive about the use of terms like "brainless ballbasher" and "pusher", and just accept that they're part of the language that is used to discuss the sport on TF, a kind of shorthand if you like.
On the other hand it becomes counterproductive when posters use these terms not as shorthand, but as trump cards, that are supposed to render all further discussion of a player's qualities unnecessary. Then again, we also have some handy terms (like "troll") to identify posters like these, so we don't have to waste too much time refuting their non-arguments.
I don't even think BBB necessarily means someone without a plan B. Venus Williams and Lindsay Davenport come to mind as players who weren't exactly known for switching up their gameplan when they were losing, but they were never called BBBs. I think having good serves to complement the groundstrokes, having pretty good net games as well helps. For me when I think of the term BBB I think of the style of play ubiquitous in the late 2000s with girls whose skillsets weren't complete enough to play a full "big babe" style like Williamses, Davenport, etc. They can't serve(high DF rates), can't volley, and are poor athletes, so they just hug the baseline, hitting hard groundies and praying they land in. When they make a gazillion UFEs it's not necessarily that they are dumb, they are just too limited in their play to do anything but exchange big groundies into the open court. Or maybe they do have the capacity to vary their games a bit, but their internal thought process is "why spend time constructing a point and risk losing it, when I could have, in theory, hit that ball for a winner?" on every. single. shot. That explains stats like 4-30
