# Multi-accounts on a Minecraft server: how to find alts A second account is not always against the rules: one player keeps a separate account for building, another has a brother who plays on the same computer. Trouble starts when accounts are made in batches for rewards, votes and bonuses. Updated: 2026-10-27 ## In short - Alts hurt the server economy: starter kits, daily rewards, referral bonuses, votes on server lists. - The easiest way to make a dozen accounts with different addresses is through VPNs and proxies. Blocking them removes most alts. - "Related players" in the profile shows nicknames from the same addresses on any Kordon plan. - The account links graph on the Premium plan finds one person's accounts by more than their addresses. - A shared address proves nothing on its own: it may be a family or a dorm. ## Why players make alts Almost always for profit. Every new account gets a starter kit, a daily reward, a bonus for inviting a friend or one more vote on a server list. Ten accounts bring in ten times as much, the resources flow to the main account, and the server economy gets out of balance. Less often an alt is used to store items, to get around a clan limit or to enter a contest several times. If someone came back on a new account after a ban, that is ban evasion. It has its own guide: [how to deal with ban evasion](https://kordonlabs.com/guides/minecraft-alt-accounts-ban-evasion). ## Rules and rewards first Decide what is allowed on your server. For example, a second account is fine, but farming rewards on alts is not. Put this in the rules, and you can ban for breaking it without arguments. The reward system itself helps too. If a reward depends on time played rather than on simply logging in, alts stop paying off. ## Close VPNs and proxies From one home connection all the alts join from one address and are easy to spot. That is why farmers hide their accounts behind VPNs and proxies. Once such connections are closed, all of a person's accounts are left with their real addresses. To set this up, see [how to block VPNs and proxies](https://kordonlabs.com/guides/block-vpn-minecraft-server). ## How to find alts On any plan, a player's profile in the Kordon panel has "Related players": nicknames that joined from the same addresses. If one of them is already blacklisted, the panel marks it. On Premium and higher the same place also has the account links graph. It finds one person's accounts by more than shared addresses and shows the strength of each link: "Probably one person", "Possible link" or "Weak link". A time slider shows the links as of the date you pick. The graph looks only at your server, so you will not see accounts on other servers. If the link is strong and the violation is obvious, you can blacklist the whole group with one button, "Block the whole group". ## Do not rush to ban One shared address proves nothing: behind it may be a family, a dorm or a mobile carrier with hundreds of subscribers on one address. Before banning, look at when the accounts joined, what they played and where the resources went. If in doubt, message the player. An honest person will usually explain who else plays on their computer. ## Try it on your server Start in observe mode: Kordon shows who it would keep out, and you turn protection on when you are ready.
