How to ban user on pinging someone? - discord.js

Question

I'm trying to make a discord bot on, when pinging the owner, auto bans the author that pinged the player. The issue is, it bans the player for saying anything, how would I make it that it'd only ban if they pinged the owner?
Here's the code.
const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '<#329005206526361610>'
client.once('ready', () => {
console.log("Wary's Defender Bot is up");
});
function getUserFromMention(mention) {
if (!mention) return;
if (mention.startsWith('!')) {
mention = mention.slice(1);
}
if (mention.startsWith('<#329005206526361610') && mention.endsWith('>')) return {
// mention = mention.slice(2, -1),
return: client.users.cache.get(mention)
}
}
client.on('message', _message => {
// if(!_message.content.users.has('#warycoolio')) return;
const user = getUserFromMention(_message.content);
if(user) return;
console.log('found target')
var member = _message.author
var rMember = _message.guild.member(_message.author)
// ban7, 'lol.'
rMember.ban({ days: 7, reason: 'They deserved it'}); {
// Successmessage
console.log('target dead.')
}
});

Answer 1

You can do this by checking _message.mentions.users with .has() and passing in the guild owner's id.
Use .has() instead of checking message content, this will automatically check the Message#mentions collection.
Dynamically get the guild owner's id using Guild#ownerID.
client.on('message', _message => {
if (_message.mentions.users.has(_message.guild.ownerID)) {
_message.author.ban({ days: 7, reason: 'They deserved it'});
}
});

You could just do a quick check to see if the mentions include a mention to the owner of the server, and then ban the user.
client.on("message", _message => {
if (_message.mentions.users.first().id === "owner id") {
message.author.ban()
}
})
