This tweet from SciresM shows how clearing error logs via nx-dreport can be considered unsafe which is why the author eventually depreciated the tool.So if I'm gathering this right, the logs are irrelevant and it's mainly not leaving traces of cfw usage before continuing online usage. Trying to clear the logs is only going to show signs of it being tampered with as it can't wipe all traces.
Then, being on ofw 8.x playing online. Restoring nand to clean 3.x and updating backup to 8.x ofw and playing online is assumed as safe due to no cfw trace.
I'm very curious to read the finer details if I could be redirected towards a technical write up. Mainly I'm curious (and might attempt with my own switch) what happens if I factory reset a "dirty nand" backup and use it as a base. I have a 3.x nand backup that I made after I had tinkered with pegaswitch to run homebrew launcher. It crashed a few times too setting up pegaswitch usually.
I have yet to be banned, waiting on emunand.

Also factory resets don't remove all traces of CFW/homebrew in your system. If you mount your NAND via hacdiskmount after performing a factory reset, you can see how many files stay after the reset.5.0.0 really upped the info in Crash Reports: https://t.co/lp9eRpva59.

Be careful with tools like dreport, too, it looks like erpt maintains statistics about reports saved/uploaded/failed to upload, deleting may cause detectably inconsistent statistics.
