Looks great! What technology is it built on? Did you reverse engineer Discord's API or is there a documentation or library?
The software now doesn't sync users to a sqlite local database if there's over 10k members in a guild, as a precaution
Discord is a pretty decent company so far IMO, I figure if they're okay with 3rd party clients then they'll be extra lenient on the rules. So far their success has been how much the community loves love (not to mention how well it works).
