1. Go to: https://steam-tracker.com/ select all delisted,removed games.
   Copy paste the whole website to excel and copy the whole name column to a .txt file.(It may take a while,so don't worry or cancel the whole process)
   
2. Banned Lists: https://steam-tracker.com/apps/banned -> do the same as in step 1
   
3. Your true Booster-pack-count(with banned games,aswell as removed ones)
   if you use this link: https://steamproxy-script.pipiskins.com/id/your_id/badges/ -> What booster packs can I get?(not this user though) you'll only get a list WITHOUT the Banned ones.
   Use this one instead.
   https://steamproxy-script.pipiskins.com/tradingcards/boostercreator/
   
   Login into your browser,use F12 and then run this script:

// Get all elements with the class name "available"
var elements = document.getElementsByClassName("available");

// Iterate through the elements and retrieve the inner text or labels
var labels = [];
for (var i = 0; i < elements.length; i++) {
var element = elements[];//add i inside the brackets

// Get inner text or label
var labelText = element.innerText || element.textContent;

// Push the label text to the array
labels.push(labelText);
}

// Now, the 'labels' array contains all the inner text or labels from elements with class "available"
console.log(labels);
You'll get an object(example below),copy paste it in some .txt file,if its undefined,your forgot the i in the brackets.

Whenever <tab> is written,replace it with an actual tab or a few empty spaces.
Or use the online variant:
https://www.online-python.com/ or https://www.onlinegdb.com/online_python_compiler

import os

file_1 = open("removed.txt", "r",encoding='utf-8')#removed games default file
file_2 = open("banned.txt", "r",encoding='utf-8')#banned games default file
file_3 = open("trueboosters.txt", "r",encoding='utf-8')#booster_real games default file

all_the_lines_1 = file_1.readlines()
all_the_lines_2 = file_2.readlines()
trueboost = file_3.readlines()

removedlist = []#default removed games
bannedlist = []#default banned list
trueboostlist = []#Booster pack drop list

for i in all_the_lines_1:
<tab>i = i.rstrip()
<tab>removedlist.append(i.strip())

for i in all_the_lines_2:
<tab>i = i.rstrip()
<tab>bannedlist.append(i.strip())

for i in trueboost:
<tab>i = i.rstrip()
<tab>i = i.replace(",","").replace('"', '').strip()
<tab>trueboostlist.append(i)

both_list = list(set(removedlist) & set(trueboostlist))#The intersection of the two sets
ban_list = list(set(bannedlist) & set(trueboostlist))#The intersection of the two sets
print("Count of removed-card-dropping-games in your library: ",len(both_list))
for i in range(0,len(both_list)):
<tab>print("-",both_list[])
#only looks a bit weird here,because steam hides anything in these [] brackets,add i inside

print("\nCount of banned-card-dropping-games in your library: ",len(ban_list))
for i in range(0,len(ban_list)):
<tab>print(ban_list[])
#only looks a bit weird here,because steam hides anything in these [] brackets,add i inside

file_1.close()
file_2.close()
file_3.close()
You may use this code to get your whole banned games,as long as you have a .txt file with the names of every game in your collection. Works for other people aswell,as long as you have their whole "gamelist".

First i want to thank the author of the removedgamesscanner.
