Wow, great job shavit.
You could optimize the use of the plugin by deleting the old ticks that cant be used,
but i am not sure if it will still be able to block the backtracking exploit ( i can't check this one ).

PHP Code:

#include <sourcemod>
#include <sdktools>

#define PLUGIN_VERSION "1.2"

ConVar gCV_Behavior = null;

ArrayList gA_TickCounts[MAXPLAYERS+1];

public Plugin myinfo =
{
    name = "Backtrack Elimination",
    author = "shavit",
    description = "Fixes the 'backtrack' exploit.",
    version = PLUGIN_VERSION,
    url = "https://github.com/shavitush"
}

int DeadTick = 0;

public void OnPluginStart()
{
    CreateConVar("backtrack_version", PLUGIN_VERSION, "Plugin version.", (FCVAR_NOTIFY | FCVAR_DONTRECORD));
    gCV_Behavior = CreateConVar("backtrack_behavior", "1", "Should the plugin be enabled?\n0 - no\n1 - yes, eliminate backtracking", 0, true, 0.0, true, 1.0);

    AutoExecConfig();

    for(int i = 1; i <= MaxClients; i++)
    {
        if(IsClientInGame(i))
        {
            OnClientPutInServer(i);
        }
    }

    DeadTick = RoundToZero((1.0 / GetTickInterval()) * FindConVar("sv_maxunlag").FloatValue); // server tickrate * sv_maxunlag value.
    HookEvent("player_spawn", Player_Spawn);
}

public void Player_Spawn(Event event, const char[] name, bool dontBroadcast)
{
    int userid = event.GetInt("userid");
    int client = GetClientOfUserId(userid);

    if(gA_TickCounts[client] != null)
    {
        gA_TickCounts[client].Clear();
    }
}

public void OnClientPutInServer(int client)
{
    if(!IsFakeClient(client) && gA_TickCounts[client] == null)
    {
        gA_TickCounts[client] = new ArrayList();
    }
}

public void OnClientDisconnect(int client)
{
    delete gA_TickCounts[client];
}

public Action OnPlayerRunCmd(int client, int &buttons, int &impulse, float vel[3], float angles[3], int &weapon, int &subtype, int &cmdnum, int &tickcount)
{
    if(!IsPlayerAlive(client) || IsFakeClient(client) || !gCV_Behavior.BoolValue || gA_TickCounts[client] == null)
    {
        return Plugin_Continue;
    }

    if(gA_TickCounts[client].FindValue(tickcount) == -1)
    {
        gA_TickCounts[client].Push(tickcount);
        if(gA_TickCounts[client].Length > DeadTick)
        {
            gA_TickCounts[client].Erase(0);
        }
    }

    // illegal usercmd->tick_count
    // you cannot have the same tick_count twice!
    else
    {
        // makes the exploit useless by editing tick_count to a random value, below the possible window for backtracking
        SortADTArray(gA_TickCounts[client], Sort_Descending, Sort_Integer);
        tickcount = gA_TickCounts[client].Get(0) - GetRandomInt(32, 64);
        
        // prevent duplicates
        if(gA_TickCounts[client].FindValue(tickcount) == -1)
        {
            gA_TickCounts[client].Push(tickcount);
        }
        if(gA_TickCounts[client].Length > DeadTick)
        {
            gA_TickCounts[client].Erase(0);
        }
        
        return Plugin_Changed;
    }

    return Plugin_Continue;
}

I don't think this is how lag compensation works. https://mxr.alliedmods.net/hl2sdk-cs...?i=sv_maxunlag
Refer to the references in game/server/player.cpp and game/server/player_lagcompensation.cpp. Although this is from AM's reversed SDK, I believe it's still accurate.

This micro-optimization seems very unnecessary (and to be honest, it causes more overhead!) as you do more calls to ArrayList.Length and ArrayList.Erase. Keep in mind that ADT arrays are very fast too.

I have no idea how this is even relevant to Backtrack Elimination.
