Amusingly, given the starting point for this discussion, what you've described part of how the "OK" sign became associated with racism. In 2017, someone on 4chan's /pol/ board suggested "Operation O-KKK": flood Twitter etc with warnings about the supposedly racist meaning of the "OK" gesture. The initial target of the hoax was the regular "are you all right?" sign, but the inverted "circle game" version came under fire as well. Later, after the hoax had run its course, those who are wont to "own the libs" used it ironically as a joke. Time passes, only the most dedicated continue to use it, and its meaning becomes less a farce and more a serious signal. (There is a similar, earlier sign used by a milita group called the "Three Percenters", but that was not the source of the spread. They are an extreme libertarian group, not a white supremacy one. Though one can imagine some overlap. Their hand sign became so closely associated with white supremacy partially because of the 4chan hoax.)
