Is that reason enough not to try? Because people will complain? You know very well that people will complain no matter what happens, yet we still must seek to work towards truth and a better way, even though "better" is in opinion word, and sometimes so is "truth."
good luck filtering human content via deterministic algorithms, and if people can reverse engineer these then they'll get gamed... it's just a stupid idea.
Back in the day this is how it worked. They changed it. Nobody that I can recall was complaining for it to change at the time. Circa 2006 I think.
edit: grammar
It was much smaller and less influential back then.
