I mean many, and I mean many, people were banned when they used .XCI files explicitly offline but updated them online while not even being in SX OS. In fact, these so called believers thought it was safe because there was no way supposedly for Nintendo to tell the difference between an offline .XCI file and a cart that you borrowed from your friend one time. But they were also proven wrong once they were all banned and nearly all around the same time too. Some of those users were doing this practice for upwards of an entire year. So its not really a matter of how but a matter of when.
Whether the questionnaire is faulty or not again is all stemming from your opinion and not objective fact. If there was such an incidence of a user misreporting something or misunderstanding something, then you might have some ground to stand on. But your viewpoint is based entirely on conjecture. Also, it was not as if I transcribed everyone's answers without proofreading them. There have been some times when people reported conflicting answers that don't make sense but I either corrected them based on the existing info or consulted them for clarification. And while the Google Doc answers aren't viewable to the public, the ones in the thread certainly are so if there's any doubts about people's answers, anyone can read them.
Lastly, as I stated, you streaming that you are not banned only proves that you are not banned in the moment for whatever you are doing at that time. It doesn't prove any of the actions you may have taken previously. That doesn't even prove your friends and family are safe for the same reasons. If you want to prove without a shadow of a doubt that everything you say you did is safe, then you would have to perform them all in the same livestream. But can you or them even remember every single little action you have ever taken? Of course not, that isn't practical. Heck if I were to play devil's advocate at your level of mistrust, I can go so far to claim that you swapped out certificates or motherboards. The point is progress isn't made by doubting everything you see, especially if its based on an opinion. The issues with exFAT, AutoRCM, and patched units all started with similar user submitted reports that were found to be conclusive. So rather than try to dismantle years of work and the effort of hundreds of users, try to let go of your bias and establish a new conclusion for the evidence presented before you.
I said myself that the past is hard to proof, and that I can only proof the present without a doubt. But still, me regularly switching the motherboard would be pretty expensive and what would the intention be, for me lying about it and wasting so much money for it.
About the xcis, you need to use sxos to do gamecard emulation, and there where some problems with sxos itself, that got probably not handled by most people, making it hard to actually identify whether it was game xcis or something else that banned them.
Main problem I remember is that it didn't include atmosheres creport, and I think at least for a while, it also didn't include fatal, through im unsure about the last part.
This means by default a lot of reports where generated, that can leak Info, that atmosphere didn't leak.
I think there where also some xci homebrew applications/mods, that used non existend titleids, and thus would lead to the same problem as nsp homebrew, logs of easy to identify invalid titles, that where only usable with signature patches.
Wherether xci emulation was actually safe enough or not, or if me buying the games shorty after release of early leaked games changed something, I have no idea. I only know, I never got banned for using them offline a few times this way, or for using my personal backups pre new card authentication online.
And for the questionnaire, I even gave you an explicit example of something the user will likely not understand in the same way, as long as they don't know and understand the intent behind it. Not sure if you worked in a job where you need to handle user reports, but users are often not an expert in the topic, their memory can be faulty and they even less can look into your head, so questions need to be as easy to understand as possible, and leave as little room of misunderstanding as possible. Just asking for a specific file format for example will likely be understood as just this format by many. That's why I often explain it differently in the list of likely unsafe things, where I describe it as installing something to the home menu for example nsp/xci files. This is likely still not foolproof, but likely easier to understand ( at least as long as the user understand what the home menu is, which most here probably do).
Also the difference to things like patched switches and the exfat problems is, that we didn't just left it at user reports, and instead we know why those problems happen on a technical level.
Same for unsafe to do things from the reswitched list, we know which traces are likely left behind, and know when those are send.
This means what reswitched says is mostly not just User reports, instead it's user reports confirmed by technical analysis.
So the data you collected is not completelly useless, but it also means it's not evidence in itself for the more generic stuff, like just using cfw with homebrew, leads to bans or your theory about random bans. User reports give us directions we can investigate deeper, and then verify or deny specific claims on a more technical level.
