A simple API wrapper for botblock.org providing server count posting to all bot lists and fetching bot information from all. [Python - maintained by @MattIPv4]
guild_ready_timeout is documented as The maximum number of seconds to wait for the GUILD_CREATE stream to end before preparing the member cache and firing READY. It defaults to 2 seconds, which means for very large bots (such as my own), on_ready can fire before the bot has all of the guilds and therefore will cause discordlists to report the wrong (and often much lower) guild count to the APIs.
maybe just mention this in the readme or setup guides? it might also be possible to use some of the code from _delay_ready() to ignore on_ready and wait for all guilds to be ready but I'm not sure how
