If a player verifies themselves in-game, so they are set to a new role on discord automatically, if they are kicked from discord channel for spamming or whatever, when they come back they are the default role, and cant re-verify.

What? Are you saying that if a person gets kicked from the Discord server, rejoins, logs in on the Minecraft server, they do not get their roles set again? I see no way this would be possible as the group synchronization doesn't rely on the person being a member of the Discord server or not, it just keeps user IDs.

I think you misread, If they get kicked from Discord server, rejoins the DISCORD server, their role on the DISCORD server that was set when they verified themselves has been removed, since they re-join the DISCORD server their role on the discord server was reset to the default. They can not re-verify from the minecraft server as they have already done so.

I didn't misread. If they want their Discord roles back, all they need to do is rejoin the Minecraft server.

Sounds like you use MinecraftDiscordAccountLinkedRoleNameToAddUserTo. If so sure, your users first needs to /discord unlink and /discord link again. To prevent them from doing so use GroupRoleSynchronizationRoleIdsToSync. Booth can be found in config.yml.

@Androkai I haven't allowed users to unlink, as I have some commands run when they link, I don't want them to be able to spam link/unlink.
I don't have GroupRoleSynchronizationRoleIdsToSync my config must be outdated! Ill update discordSRV and add it.
