Secure groups

If this is used by streamers, viewers seeing the link will be able to join the group, which is probably unwanted.

I still want to keep the link system because it's simple.
But we need a way to 'secure' it.

I thought of a couple of ways:

1. Require signed in RIOT account, and the owner of the group invites using RIOT IDs
   • This is really bad because it creates a lot of friction which makes the system annoying to use.
2. A validation system with a buffer channel where the owner of the group accepts or deny each player when they join the Discord.
   • This could work but still isn't perfect
3. Some sort of hard to read code in the link, could be a series of lowercase L and uppercase I, non-latin characters, etc..
   • Could work but not a perfect solution either
4. Streamers hide champ select chat
   • Can't enforce, still annoying for them if they forget

A potential issue of using non-latin character is that they carry meaning, and chaining them together could result in unwanted interpretations
