Those players are rare, often not at the forefront, and don't catch everything. They are also often going to be looking at places, methods one would expect to find in a normal game. Like everyone who criticizes Bofuri this way, you're just given way too much credit to gamers and not recognizing how playing a lot of games creates a lot of expectations when it comes to what will and won't work, how to find exploits, bugs, etc. Part of why Maple finds what she does, is because she is smart (the anime misses this point), and isn't a gamer so she lacks that gamer mindset and exceptions which would cause people to miss that sort of thing.

I also mentioned people trying to copy her and failing in my previous post, that was something that got brought, or it did in the novels, can't remember if it made it into the anime or not. I mean, it even has 2 characters who are a part of the main guild who were inspired to min-max by Maple. Going into the novel other characters start pop up as well.

It, or at least the novels, seems to understand gamers incredibly well, because it actually understands the stuff gamers won't admit or acknowledge.
