Without details such as Server and NoCheatPlus versions and also what checks are spamming we can't say much in most cases. For chat it really matters what you want to allow people, current spam features do constant slower paced spamming.

If your players can hardly chat, then something is wrong of course, if you want them to send 40 messages per minute each, then you have to adapt the configuration. We just need more details about what actually happens. It could be you are using an incompatible Spigot build or are having conflicting plugins (doubling the chat events by canceling and firing new ones). Recently you two have brought in the only complaints on this, so we can't necessarily say that the settings are all that bad. Though i am indeed planning on more systematic tests with the anti spam features, simulating server chat to find the best config values that still provide protection.

@Gnacik

Latest Spigot = surprise , please always give the build numbers etc.

In fact in this case the related CraftBukkit build number decides on what to do.

I assume latest Spigot is like CB 2514 about, so you need to use the GitHub download:
https://github.com/NoCheatPlus/NoCheatPlus/downloads

Thanks to an ingenious decision by Bukkit team we have to improvise.

@mrchasez

Which version ? Does it have the "/ncp lag" command (latest dev builds at Jekins / GitHub downloads)?

You could check the result of that command in such a situation.

It could be the effect of lag spikes, but the image also can show a client with a problematic connection or even a cheater.

Does "when ever someone" really mean all players always?

@rsmKaelub

No need to apologize, quick question, maybe a quick answer.

The latest version on BukkitDev (b271) as well as a range before do have anti vclip. The Passable check does that, it also alerts on login, becasue players already move before having received chunks.

Provided the players can't move more than the wall-thickness at once (normally can't, but with allowing them to fly fast it might change).

Details:

There are no interpolation tests, just start end endpoints (taking into account some specialty of CraftBukkit leading to sometimes having a different position than the moving events contain, thus up to 3 points). Doors and thin mechanisms are also all unsafe, thus real no-clip protection will need a thorough piston setup or tp through walls to prevent others ever entering a protected ground without need to always re-placing blocks. Also mind that moving diagonally (hacks) might bypass a diagonally set up wall:
ox
xo

But just to prevent direct passage 1-thick walls should suffice. Corners and piston entries need a little more care, i assume some clients are able to do the (pretty exact) diagonal move).

Concerning the CB 2511 -> CB 2512 change:

Try the experimental 1.4 compatibility build:
https://github.com/NoCheatPlus/NoCheatPlus/downloads

I have tested it shortly, but the range of mostly necessary changes might have lead to some more fish than i already caught.

Be aware that any other plugins can break randomly from CB 2512 on (if they are not only using Bukkit but access CB or MC).

@Togakure321

This plugin does not ban. You can use "/ncp unkick player" against the chat short-term kicks. Also "NCP kicklist".

Are you using any other plugin that might hook into NCP and start banning players in the name of good ?

If it is NCP: Check the logs (server and nocheatplus.log in the plugins/NoCheatPlus folder) for kick / ban entries, also the checks that lead to kicking should be in there. Then adjust the config to your needs - if you want high chat frequency you have to increase the levels.

@Dasko222

NCP does not do anything against xray. Serious anti xray should need an extra plugin(Orebfuscator, Anti X-Ray, DarkTrace).

@ShakyTom

I probably won't quickly. Keep to CB2511 til then. In fact i already evaluated a compatibility version and committed an untested and non-compiling "half-state" to GitHub, taking one or another couple of hours prematurely (changes were not scheduled for now, hurts).

Unfortunately i have to change the build process to get this thing working in a reasonably convenient way, and i am not too familiar with maven. Also i think after this i wrecked the project setup and i will be away for one or another day very soon.

If anybody has experience with setting up the project with maven (or say,... gradle) such that i can have the compatibility packages compiled with different CraftBukkit versions (same artifact ids under maven...) while main core is Bukkit API, all in one integrating with Jenkins, i might appreciate some help on this. The interfaces are not self explaining, neither the tutorials i read or rather not read, i can't sit hours on that now.

Maybe i put a "CB2512" version on GitHub (hand sewn). But it contains a range of internal changes due to this CB policy change, that i cant test myself at present.
