I don't understand about some people who have saves and unwilling to share in here, even if it isn't related to online or account locked saves.
I can totally understand about ACNH but for most other games, no.
A lot of requests in this thread has been unfulfilled for months and years but first party games likely to see saves immediately or sooner but not much with third party games.
I'm very sorry if it didn't meet your expectation but anyone who have save and upload in here if they willing to do, even offer to give money won't work due to no response.
Remember, I don't offer a service to upload the saves in your account because I have no experience, possibility increase of ban risk if Nintendo know about numerous uploads with different accounts on same Switch console, even your accounts could get a ban too, so I don't want to be liable about what happen to your account and don't want my Switch to be banned. I recommend you to buy hacked Switch tablet or put mod chip in Switch, or ask your friend nearby who has hacked Switch. Please don't PM me about it and no, I don't take money either. I don't believe in profit over save or upload service.
