its not some pattern of abuse by shady actors manipulating opinions youre noticing, its voting algorithm and attention economy itself.
new ideas are constantly being published, and popular ones gain momentum by being shown to more people. as the idea gets saturated, the popularity gets overshadowed by the time based downranking.
if the idea is still popular though, in this case that ice murdered some woman as part of their shock and awe campaign, variations are going to show up such as "legal observer" and "mother of a three year old"
basic correction below:
<< murdered
shot/killed
<< as part of their shock and awe campaign
law enforcement operation
<< its voting algorithm and attention economy itself
Sure, and yet we have people skilled in manipulating both for their own ends.
