Thread logs via modmail API

[fourjr]

• Centralised MongoDB accessed through Modmail API
• API token has to be added in config variables (generated from kyber website after github oauth)
• github callback checks if github user forked repo?
• Logs are hosted on logs.kyb3r.tk/github-user-id/randomstring

jwt stores:

• github access token
• github username

get log random string:

import secrets
return secrets.token_hex(6)
