Minecraft anticheat guide
Anticheat for Skyblock and Prison Servers
Which cheats damage Skyblock and prison economies, which checks to enable first, and a staff workflow for block-break and click alerts on grind servers.
What do cheats break on a grind server?
On Skyblock and prison servers, cheats mostly damage the economy rather than fights. Fastbreak and nuker clients mine faster than the held tool allows, which inflates ore and farm output. Autoclickers automate grinding, so players earn rewards without playing the loop your balance assumes. Enable block-break and click checks first, keep them in alert-only mode, and review the economy changes that match each alert.
Economy damage builds slowly. One fast mine is easy to dismiss, but a player who clears a mine every few minutes for a week can move a large share of the server's currency. Staff usually notice market prices shifting before they notice the cheat. That is why the anticheat should watch block breaking and click patterns from the first day, not after the first complaint.
| Cheat or exploit | How it damages the economy | First check to enable | What staff confirm |
|---|---|---|---|
| FastBreak or nuker | Breaks blocks faster than the held tool allows, inflating ore and farm output | Block-break timing and burst checks | Break count against the tool, mine layout, and any active haste effect |
| Autoclicker on grinds | Automates mob farms, crop harvests, or repeated block hits | CPS and click-interval checks | Click pattern over a long window, not one spike |
| Inventory or chest stealing | Moves items out of shared storage or player vaults | Inventory and chest checks | Whether that player could reach the storage at the time |
| Reach through walls on mob farms | Hits or collects from positions the player should not reach | Reach and occlusion checks | Whether the target was visible and in range |
Which checks should you enable first?
Turn checks on in an order you can review. Enabling everything at once makes the first week of alerts hard to read and hides the cheats that matter most.
The first alerts teach staff what normal looks like. A new player's sprint-jumping, a farm's ordinary break rhythm, and a real nuker can all land in one queue on day one. Two checks reviewed well are worth more than eight checks nobody reads. Add the next check only after the first two have a known baseline.

Review alerts as a sequence. One alert from a player who never repeats the pattern is usually noise. Repeated alerts across several mining sessions, with economy changes that match, deserve a closer look.
Keep the review short enough that staff finish it. Write the decision before taking action, so later reviewers can see what was known at the time.
Pay particular attention to mine resets. A player who mines hard right after a reset is normal. A player whose break count stays flat across several resets while their balance climbs is worth a closer look. Record both observations, because the second one is the pattern that matters.

We have not measured false-positive rates or detection accuracy for any prison or Skyblock plugin, and we have not tested your economy setup. The steps above are a review process, not a promise of results. Run them on a staging copy of your server with the same grind plugins before you rely on them.
Where FairPlay fits
FairPlay documents its PacketEvents installation, its checks, and its mitigation settings in the docs linked from this article. Read the checks reference and the mitigation configuration before you decide whether it covers your grind loops. Compare it with other anticheats on a staging server using the same economy test, and do not treat the docs as evidence of performance.
FAQ
Will a fastbreak check flag a player using Efficiency or Haste?
It can, if the check ignores the held tool's enchantments or active haste effects. Confirm that behavior on staging with each pickaxe tier before you treat a break alert as a cheat.
Should we exempt TNT mines from break checks?
Exempting the whole world removes coverage where nukers often hide. Exempt only explosion-driven breaks you can separate in your logs, and keep hand-mined breaks checked.
How long should an autoclicker alert window be?
We cannot give a verified number. Choose a window that spans several grind sessions, then compare it with a staff control session before acting.
Do grind servers need to punish on the first fastbreak alert?
No. A first alert is a review signal. Use warnings or mitigation for repeat patterns, and keep bans for cases your staff have verified.
Does alert-only mode change player balances?
No. Alert-only mode logs suspicious activity and leaves break, click, and economy results as they are.
