What is CasualProtector?

• This plugin protects your server from bots (antibot and antivpn systems), exploits (lags, crashes caused by hack-clients, e.g jigsaw or jessica etc.) and optimizes tps, fps, reduce lags! We support a lot of mc versions (1.7.x-1.14.x)
• The only thing what the plugin wants from you is install ProtocolLib(it is required for packet listening)
  Spoiler: protocollib version
• We protect against bungee exploits! (e.g. www.youtube.com/watch?v=_vNuZux_c4k, pastebin.com/raw/tjP0DPd2) Please read bungee exploits section. (If someone crashes your server (with a lot of bots or something like a ddos/flood) and you get such errors: https://pastebin.com/raw/tjP0DPd2 or similar ones - please use my fixed waterfall from readme.txt file.
• Since 3.9 we check the redstone and limit them! It really optimize server tps and game perfomance! There are redstone exploits that a lot of newest versions doesn't block just because it's more like a bug. Look at redstone checker section

FEATURES

• Blocks bots (a lot of ways to block bots, look at antibot section)
• Blocks exploits, lags, crashes (look at antiexploit section)
• Blocks some flood packets (like ddos/dos - remember that we don't block all ddos/dos attacks! You have to block it in another way like iptables or something else, we only check flood packets)
• Vpn/proxy/bad ip checking (a lot of configurable ways to block it, you can add your own ip checking! You can set the url and result you want to get)
• Block flood attack (MCSpam etc.) - edited proxy and spigot code.
• Reduce/remove redstone exploits (redstone checker section)
• Allow only specified countries to join (e.g poland, china or your country)
• Supports bungeecord! Are you running bungeecord? Put the .jar file to your spigot and bungeecord servers!
• Optimize lags, tps
• Optimize fps - hiding falling blocks like sand and tnt. (really helpful)
• Blocks mods like worlddownloader, labymod, liteloader, forge etc.
• Configurable - The plugin is almost fully configurable! There are configuration files like:config.yml, messages.yml, messagesbunge.yml

Spoiler: configuration files (.yml)

ANTIBOT SYSTEM:

• There is an accounts limit for accounts per ip (configurable) - if player exceed it his connections to server (also his bots) will be cancelled with specified reason.
• Vpn, proxy checking - we send a http request to API's that respond very fast with the result (bot or normal player) - you can disable vpn/proxy detectors in bad-ip-checkers section in config.yml. You can add your own ip checker, it's very easy, just take a look at already existing detectors in the section.
• Checking last player's name length and compare it, if there were too many connections with the same name length - bots will be not able to join
• Compare half of player's name with online players' name, if these are similar - more bots (with similar nicknames) will be not able to join.
• ConnectionThrottle - 1 address can connect to server every 15 seconds (very useful) - obviously you can change the delay. (we recommend to set connection-throttle in spigot config to -1)
• If player name is similar to 3 other players' name he will be not able to join, e.g "1283217juniks_ 812372123juniks_, deathbot122, etc.." - the next bot will be not able to join, and bots will have to change their nicknames.
• If player is using vpn or proxies ip he will be not able to connect to the server (configurable)
• Player has to connect again to server if he is newbie (double-join/re-connect) - deathbots and other bots without double-join will be not able to join. If he is verified he doesn't have to re-connect again.
• Plugin checks first packets from player - if these are recognized as invalid (or are sent too late) - bot is kicked and his ip is blocked for 10 minutes.
• There is a pingchecker! If player's ping is bigger than set and tps are above 19.8 he will be kicked. Often bots have very big ping so they will be kicked from the server.

ANTIEXPLOIT SYSTEM (what do I block):

• Nbt exploit (mainly hacked items like written_book with too many pages etc. (windowclick, blockplace spam etc))
  Spoiler: small info about nbt exploit
• Packet-Filter checks all Client packets and their InputBuffer#remaining, really useful feature, blocks most of exploits.
• Run commands (e.g in books, executing commands without player permission - adding to plot, paying money etc.)
• Firework exploit (too big Flight size that crashes the server)
• If there are more than XXX tags in nbtCompound - nbt is recognized as invalid and event is cancelled, player is kicked
• Spam packets: register, arm animation etc. if there are more players = arm animation exploit works better, more packets = more lags - i did a time period between sending arm animation packets and some more. (since 1.12 it's useless)
• Invalid packets.. e.g: client position, player can send invalid position packets, e.g too big x,y,z coordinates (or pitch and yaw)
• Payload exploits (like too many register packets, or too big size of channels, too big mc|bedit data etc.)
• Checking last 50 windowclick packets. If they are very similar (and the space between each packet is less than 0.5 sec) player is disconnected. Useful for detecting spam packets.
• Sign exploits (too much lines, characters in sign etc)
• Command exploits like worldedit commands (//calc with arguments etc)
• Hacked items (too big enchantments/over-enchanted items or amount of item)
• Hopper creative crasher (common on creative servers, when hopper is placed noone can join on the server until server administrator will remove the world data)
• Buffer overflow - something like nbt exploit, you can read more here: https://en.wikipedia.org/wiki/Buffer_overflow
• Fix skull (skullexploitpatch code used) and chunk exploits
• Fix armorstand and egg exploits
• Fix duplications like book, sign
• Command exploits (like pex or worldedit)
• Anti logged from another location (if we can call it exploit)
• UUIDSpoof exploit (with cache-system)
• Custompayload (jigsaw and many more)
• Player's ip is blocked from joining on server for 10 minutes if he tries to crash server
• and many more! (This plugin was specifically created to prevent exploits)

REDSTONE CHECKER
How does it work? It's simple. I check the redstones in every chunk. If the redstones amount is too big (e.g 50) the plugin just unpower (unactive) the redstones in current chunk. I also limit the clicking in lever, one click is limited to 1.5s. But how much awesome would it be when I wouldn't add some fun things! That's how the /redstones command looks like.
