The Elo system firstly is not entirely accurately done here, in my eyes (weighting-wise) and there were many issues earlier on as grudge-voting disguised as genuine voting was a major issue thanks to quite a few users, the most prominent one who did it nonstop to me was Ramshutu, he also is a major reason why Oromagi won as much as he did (they voted for each other but to be fair to Oromagi, I believe that he believed his votes whereas Ramshutu was blatantly slanting utter nonsense angles to justify his votes). There was a clear cut win-win relationship between Oromagi, Ramshutu and Ragnar, with Ramshutu being the one who most knowingly and ruthlessly did the bullshit voting scheme.
Ramshutu quit this website mysteriously soon after the old head mod (who always ruled in favour of Ramshutu and even modded this corrupt guy) was dethroned. I think it had to do with Virtuoso not letting him prey on me so easily and Ragnar changed after he got his role as deputy mod into a far fairer and wiser member of the community. Why I specifically call out Ramshutu is to explain that the Rating you see on debaters who had a lot of debates was almost 80-85% controlled by Ramshutu's whims as he dedicated to voting on everyone's debates and stalled ever debating at all for many months of his site membership, planning carefully who to build rapport with and who to prey upon without letting them fight back as he picked his opponents and topics extremely carefully.
