Is "hardstuck" a neologism? What is its etymology?

I have used the word hardstuck to mean "permanently unable to move". It is a more intense version of stuck, since stuck can sometimes mean "temporarily unable to move" or "unable to move without extended effort". For example: "I am hardstuck on this coding problem, can you help?" meaning "I have no hope of solving this coding problem, can you help?".

I have heard hardstuck or hard stuck primarily used to describe the situation where a person is unable to move up and out of their current rank in competitive online gaming, and I assume that it is a neologism.

Is it a neologism? What is the word's etymology?

Google Trends indicates that the term gained usage in the U.S. beginning in 2017.

It looks to me like this expression originated in the League of Legends community (which is still the gaming community that uses it the most, it seems). All of these are in reference to rating, which at the time was the Elo rating system.

So far I found something as far back as late 2015 via Twitter:

we are same pisselo only difference is u have 2k games HARD stuck next time u shower i hope it come gas — November 18th, 2015

Examples are much more plentiful starting in 2016, as this Twitter search shows. Late 2016 is also when I first found an example of it being written as one word:

Here are some more early-ish examples from across the web:
