Yes it is because precisely we are fans, we became knowledgeable about the sport, its history of political incentivised judging to know when something funny is going on: who is overmarked, who's undermarked, which event has a history of being overmarked, undermarked etc.
I watch the sport for the skaters, not the judges. Given judges are human, human errors are not inconceivable, and other than 'deliberately cheating', 'subconscious preferencing', and 'national duties' - judges can also be influenced peer pressure, professional pressure, political pressure, cognitive latency, brain freeze, crowd influence, tano pressure, and KGB pressure.
As for 'cheating', are we talking about 'theory' or 'legality' or 'reality'?
Yes it is not cheating if I own the technical panel and decide to change the rules whenever I want however I want, and have final say on all rule changes to advise my countrymen to start training juniors for a particular style, elements 2 years ahead of time that can gather easy points, while neglect to tell everyone else. So when I finally make such rule changes with no provision period - such as 10% half way bonus, and tano +3 goes, increase on 3T, 'others' are at a disadvantage since they will need 1 or 2 years to wake up to adapt to it, train for it, choreograph for it, fully getting used to it.
Yes it is not cheating, if I decide to undermine my countrymen's greatest competitor by exploiting their weakness through rule changes, and minimise their scoring opportunities, and bridging scoring gap by reducing the scoring for difficult triples, raise score for easiest triple and advice my countrymen to train consistency on the easiest triples with tons of transition for transition's sake while making GOE qualities a thing of the past.
Yes it is not cheating, if I decide to make my country most competitive by 'legally' instill judging panels consist of 100% European judges 'randomly' at the most critical events consecutively like the world championships to mostly benefit my countrymen where they can inflate their score the highest through 'personal preference', 'cultural preferences', 'nationality preferences', ' national duties'.
Yes, it is not cheating, when I am the 'law' and I make the calls, and decide to put my strictest technical caller at many of my country's biggest rival nation's competition while at my own country the most lenient and generous callers.
Yes it is not cheating, when I decide no one can challenge my decisions by writing it into the rule book, all judging are final, all judges are not accountable, anonymous, and can not be challenged.
Yes, it is not cheating, when I decide to advise and influence when I please at my own free will to disclose favourable advice and 'privileged' information; that can really help 'scoring' for who I want when I want, while handicapping others.
Yes, it is not cheating, when I do it and nobody can find out or challenge me.
Taking/Prescribing 'performance enhancement' advice is not cheating, it is only cheating if you are found out and then somebody made it illegal.
