private boolean checkSpamCharacters(String channelName, String content)
{
    if(!Config.getContains(EConfigs.CHANNEL_SPAM_CHARACTERS_BLACKLIST, channelName)) return false;
    if(content.length() <= 10) return false;

    //Count all the characters in the message
    Map<Character, Integer> characterCount = new HashMap<>();
    for(char c : content.toCharArray())
        characterCount.compute(c, (character, integer) -> integer == null ? 1 : integer + 1);

    //Add up all of the major repeated characters
    int spamCharCount = 0;
    for(int charCount : characterCount.values())
