Signal weights
Signal weight: young accountNumberAdvanced	0 disables this signal.
Signal weight: no avatarNumberAdvanced	Added to the score when the account is still on Discord's default profile picture. 0 disables this signal.
Signal weight: numeric usernameNumberAdvanced	Added to the score when the username ends in four or more digits. 0 disables this signal.
Signal weight: join correlationNumberAdvanced	Added to the score when two or more other young accounts joined in the last 5 minutes. 0 disables this signal.
Signal weight: name like a removed memberNumberAdvanced	Added to the score when the username or display name is close to someone this server banned or kicked (from the bot's own records, the latest 500 people). Letters that look alike, digits used as letters and separators are ignored. 0 disables this signal.
Name closeness needed (%)NumberAdvanced	How close two names must be to count, in percent: 100 means the same once look-alike letters and separators are ignored. Names shorter than 4 letters are never compared.
Also compare with current membersOn or offAdvanced	Also flags a name close to someone already in the server, such as a staff member being impersonated. Uses the names the bot keeps for the statistics pages (the 1,000 most recently active members), so it needs a statistics module on.
