Accepting a new person works in such a way that a new person is proposed by one of the current members. The other members then accept the candidate. When a sufficient number of people accept a new person – the system sends an email with a password to the new person.
The number of people accepting a candidate is calculated as a percentage of the total population (currently 20%). Therefore, the new person after admission should also accept the existing people. Without it, people who are in the system for the longest time and have the fewest votes can be kicked out because they will fall below 20%.
This is not a disadvantage of the system, but its advantage. It's not just the existing people who have to accept the new person. The new person must also accept the existing members. There is a compulsion to accept each other.
