why do i need to scrounge around for invite links?
if you mean something more than just the BL community a google search gives you some custom websites of lists and lists of servers:
https://discordbots.org/servershttps://discord.me/ (forgetin' nobot...)
https://disboard.org/serversforum topics opening communities usually present public invite links to public communities as well, you don't need to "scrounge" around for anything
if you mean private cliques everywhere, i do not see the consequence of making a friend inside the BL community and earning the trust of them giving you an invite link to said private cliques
without having to seek out people for a stupid invite link or dig around forum threads for something which may or may not be an awful server and not worth the time it took to join in the first place.
i have not seen anyone do this in discord
