There was a banwave around the time firmwares 6.0 came out that even affected users who only used homebrew, however most of these homebrew-only bans are related to those who updated their firmware with ChoiDujourNX. In short, updating to firmware 6.0 before connecting online most likely flagged these people for a ban since its currently impossible to update to that firmware offline without hacking the system.
Of note, .NSP only bans are on the rise as well so if you want to minimize your chances of being banned, a clean NAND backup is the best way to go. If you don't have one, you can either do a factory reset to remove fake tickets installed into your system or manually remove the software and the fake tickets via Tinfoil.
EmuNAND is too new to have any practical data about its safety however I have outlined some concerns with TX's implementation which you can find below:
Thanks a lot, i dont use NSP files, just XCI and for now, everything looks good. I edited my last message, i got error 2016-1100 saying that i need to update first, same if i try to enter eshop. I guess thats good cause i dont get any of the other error codes for banned peole.
So in conclusion, EmuNAND is no go for now, till we learn more.
Thanks again!
