No equality operators for IUser (and possibly others)

This makes it impossible to use LINQ and other built-in methods for ensuring that objects are equal to each other. Will submit a pull request with this.

IReadOnlyCollection<IUser> usersReacted = await msg.GetReactionUsersAsync(emote.Name); // Returns list of 25 users (subset of everyone in guild)
IReadOnlyCollection<IUser> usersInGuild = sguser.Guild.Users; // Returns list of 50 users
IEnumerable<IUser> usersToRemove = usersInGuild.Except(usersReacted); // Should return everyone in the guild except those who reacted

usersToRemove ends up being the same as usersInGuild. I’ll try and find a less-painful solution than doing things manually.

Thus, the only kind of thing I can think of doing is writing my own method that steps through both collections and only takes the unique values based on ID

.Except() (and just about every other LINQ method) has an overload that takes in an IEqualityComparer<T> at which point you can just do something like this. No need to write your own methods.

Should probably be closed now that comparers have been added.
