There are many problems with the very structure of a debating website. To begin with, most human beings dislike interacting in an environment where everyone is arguing (obviously). This alone means no matter how well it's done, the website will forever remain unpopular vs almost any other forum of its tier.
The other problem is that due to the anonymity of the users and thus 'worthlessness' of achievements (but not monetarily I mean even for glory for you as a person IRL) the kind of things you engage in 1v1 debates involve so much wasted effort and often saying stuff you don't really believe just to scrape out points (I am unique because I simply pivot BoP if I'm vs an opponent who slipped up so I rarely have to flesh out points I don't agree with just to 'win' but even then I have had debates that represent points of view I don't personally feel proud to show off nor the content of my opponent... to people I know IRL).
This kind of 'competitive environment' is one where we are seriously a select few humans out of a select few humans who even give enough of a shit about our Rating/Ranking to even begin to fathom discussing which medals matter.
I will always be that weirdo though and in life, for me at least, it helped me structure what was otherwise a chaotic ball of energetic and fruitless motivation. Rather than just be angry with the world, I became angry with myself to failing to understand why I was failing to compete in the world, in a website and anything. I am what I am and apply myself uniquely to an environment to excel in ways literally no one except me can.
This is something I am proud of even if the 'achievements gained' are worthless to all (including me). It's about mastering strategy in and of itself and applying myself and my unique tactics, it's something I enjoy and will do to the very day I die (and beyond, depending on how much of this persona remains in the afterlife).
I am not win-addicted, I am addicted instead to understanding the mechanics by which winners vs losers in any given environment are decided. Once understood, I don't mind being a loser anymore. I am more INTP than INTJ and that will always be the case, I am sure. The J has increased with age though and I certainly apply myself better than I did in my lazier times.
To me 'laziness' is an illusion by the way, lazy people are merely people who passionately dedicate themselves to avoiding what needs to be done. INTPs are often extremely hard-working inside their heads, it's just that they fail to apply it to anything that (as zedvictor says) 'matters'.
