How do I create my combolist?

I looked for a few videos on youtube before posting here, but they seem ineffective. I'm trying to learn how to crack accounts (I need nordvpn) and I don't know which applications are more effective. The only resource available to me are proxies. Can any of you help me?

From what I know, I need:
-combolist
-proxy
-config (I miss this one as well and would like to know how to create it)

ok i am beginner too, but i gonna try to direct you in the right direction

Config: first you need to know what app you gona use for cracking i use Open bulet anomaly mod, it is very simple to use and you can find tutorials for making configs
on youtube, (it is very simple ) but if you want to crack mainstream sites use a pack of configs, you can find some here.
if you do not have an account for the website you want to make a config for, focus first on the denial part, when you get an cracked account, you can make adjustments.

proxy: you can use proxy scrapers like this one or buy private ones (will be more reliable and efficient).

Combolist: you have alot of options here. You can buy private, find public ones like in the mpgh forum, you can also find semi-private combolists in servers and forums with a more closed list of user,you can make your own using wordlists or cracking unsecured sites using sql injection or other methods of cracking in the users database.

maybe its too late now(3 weeks), but hopefully will help.
