Context: I linked this in a Reddit comment, as an example of how little code is necessary to start automating moderation yourself

ftfy.js

const { Client } = require('discord.js');
const token = 'YOUR_FANCY_DISCORD_TOKEN';

client = new Client();

const spamBotUrls = [
    'privatepage.vip',
    'nakedphotos.club'
];

client.on('ready', () => {
    console.log(`Logged in as ${client.user.tag}.`);
});

client.on('message', msg => {
    if (spamBotUrls.some(url => msg.content.includes(url)) {
        msg.delete();
        /* Optionally ban:
         * msg.member.ban('Detected Spambot URL');
         */
    }
});

client.login(token);
