Hi, I'm offering a client mod that allows you to do the exploit similar in effect to bаn books that "bans" players/admins - affected players cannot rejoin the server without intervention (needs to remove or edit player data file). The client is based on 1.12.2, re-creating it for other versions can be discussed. It's Forge-based and works on Survival/Creative Spigot servers* (I can conduct testing on a target server before purchase). The mod has a workaround for NoCheat and is semi-automated. The proceeds will be donated to the authors of the cheat client that I extended. Note: I wrote the modification myself, not the entire client. I can answer some questions in this thread. For more and Proof (of Concept), contact: via PM here.
