This is part of the entry form that needs to be filled out in order to access the Tsuki Official discord. It detects if you are a member of Apollo, and does not let you join if you are.
Any members that are part of Apollo but filled out the old form get booted and need to fill out the new one, and in order to do so they need to leave Apollo.
I never thought I'd see the day Tsuki would stoop so low to stop people from joining his own discord for being part of another one, even if they do nothing but lurk there.
Their way of identifying is suspected to work like this: They set up an alt on Apollo, they somehow bind it to a bot that takes a look at all the members of the discord, and they send that list back to the form. If you are in that list you can't complete that form until the bot registers you are no longer in it. A usage of a bot like this, if our suspicions are correct, is against the Discord ToS.
For all those that feel they'd rather stay in official, I can totally understand that. But there's still ways to stay in touch with Apollo.
1) You could set up an Alt account, name it whatever you want, and then join Apollo with it. You can lurk or interact all you want as long as you keep it separate from your true identity and avoid visiting systemspace.link or any websites that may scrape your IP
2) Use the apollobase.neocities.org website to recieve news even if you can't join the discord
3) Create an account in [matrix] and communicate using the discord - matrix bridge bot we've set up
EDIT : The bot seems to have been disabled
