Notice of amendments to some invitation-related rules

Maybe students feel that it is a waste if they don't use the invitations they got for free, so the harem of invited people is mixed, and there are many fakes.
Fresh blood is indeed the root of the vitality of the site, but why invite someone who doesn't even read the rules and only asks for mana when he enters the site, and can't even pass the assessment after a month?

So, in the future, no more invitations will be added for all level upgrades. If you think that person is worth inviting, please buy him with mana.
From now on, if the invited person is banned more than three times, his invitation qualification will be permanently revoked.
