I mean I've done it before and I'm still not banned yet so I don't see the issue of handing out personal advice? This seems more like a you issue than a me issue. Not to mention that there are plenty of other people who have advised at the very least for using Daybreak since it emulates the official way of updating so well. So if you have an issue, take it up with them and not me.
Yeah, not banned yet. It's a completely unnecessary and pointless risk. Daybreak is a successor of choidujour, both of which were never intended to be used on a clean sysNAND. If, for some reason, you elect not to use emuMMC (or emuNAND) and want to use CFW with your sysNAND, you need to make sure that you never connect to Nintendo's servers, or your sysNAND backup will become useless for future online use.
It's unnecessary risk to use sysNAND with CFW and HB which is dumb considering that emuMMC and emuNAND exist for that reason. I can find no reason why anyone would promote putting their sysNAND at risk for no reason--which is what you are doing.
