The author posted a review of you shortly after your review or fifteen years later? Both are bizarre and messed up, I'm not even sure which one would be worse.
This is why I've moved away from arguing with people on the internet, because there are too many people out there today who are absolutely deranged and will make it literally their life's mission to stalk you through every means at their disposal.
Also - mostly thanks to discord - it's trivial to summon an army of kids who are under the age of criminal responsibility who will do almost anything (online) if you kick them a few robux.
it may not have elicited quite the extreme reaction. a 3 can be harsher than a 1.
while an “unredeemable moron” might leave one star, that may not meet the bar for a response. while fighting with idiots on the internet is a past time, it is typically one entertained by… idiots.
a three star review, on the other hand. no, this takes thought. a thinker left that harsh judgement. a foolish thinker, but a thinker. thoughtful, but wrong, incorrect. flawed. no mere idiot, so it must be an asshole. and we can’t have that. justice must be preserved.
