Ban Risk:
Instant ban:
• Piracy of any sort
• Homebrew nsps
• Changing user icon through homebrew
• Sketchy eShop behavior
Not so instant ban, but still a ban:
• Modding online games
• Cheating in online games
• Clearing error logs after they've been uploaded to Nintendo (this may extend to using both emummc and sysmmc online, due to mismatched logs)
Not a ban, so far:
• Atmosphere itself
• Homebrew
• Custom themes
• Custom sysmodules (sys-ftpd-light, etc.)
• Mods/cheating in offline games
• Overclocking with sys-clk (just don't do it competitively, for all of our sakes)
• emummc
We just don't know enough yet:
• Screwing with PRODINFO, but NOT committing bannable offenses
• Using the experimental PRODINFO dummying included in Atmosphere 0.11.2 and later.
