Interesting alternative to SteamWorks, in case it ever breaks for whatever reason. Anyways, here's my go at it. It worked correctly when I was using a family shared account, although I never actually tested it with a non family shared account.
Requires the socket extension
PHP Code:
#include <sourcemod>
#include <socket>
#define HOST_PATH "api.steampowered.com"
#define MAX_STEAMID_LENGTH 21
#define MAX_COMMUNITYID_LENGTH 18
new Handle:g_hCvarAppId = INVALID_HANDLE;
new Handle:g_hCvarAPIKey = INVALID_HANDLE;
// The maximum returned length of 174 occurs when an unauthorized key is provided
// Header length really shouldn't be 900 characters long. But just in case...
new String:g_sAPIBuffer[MAXPLAYERS + 1][1024];
new Handle:g_hAPISocket[MAXPLAYERS + 1];
public Plugin:myinfo =

name = "familyshare",
author = "bonbon",
description = "Ban family shared accounts (windows)",
version = "1.0.0.0"
};
public OnPluginStart()
{
g_hCvarAppId = CreateConVar("familysharing_appid", "730", "Application ID of current game. CS:S (240), CS:GO (730), TF2 (440)");
g_hCvarAPIKey = CreateConVar("familysharing_apikey", "XXXXXXXXXXXXXXXXXXXX", "Steam developer web API key");

Just put "familysharing_apikey <Your API key here>" in your server.cfg, as well if you ever run this on a different key make sure to change familysharing_appid as well
