Try using Simple Proxy Tools for gathering proxies. Once you open Simple Proxy Tools, click grab proxy, and once its done grabbing proxies, click the Check Proxies tab. Now click "Load Proxies From Scraper" and the proxies should appear in the thing that say's "SCRAPED/LOADED". Now click "Check Proxies". Also, don't download usernames off of the internet, scrape them using a program like "Lemmywinks Scraper". (Thats the best one in my opinion) When you open Lemmywinks, just check "Scrape forever" and "Sort servers" scrape forever just keeps scraping usernames of people who join, so it keeps scraping until you stop it, so that means just leave the scraper going for around 1-2 hours. Now wait till you have around 2500+ usernames, and try cracking them with the 30 password list in the EGG.CRACK folder. (I said folder cus there is a link to download a file with all of the best cracking tools at the end of this) So this should work, oh and in EGG.CRACK, set your Max Threads to between 200-300, it speeds it up ALOT, but it slows down your internet, so don't set it to like 1 million, or else it will just crash your internet.
Here is a link to the download of a folder that has all of the best cracking tools -
Sorry I can't send links, just go on youtube, search for my friends channel "Creeper360Bill" click on his video How to crack minecraft accounts (Non-simplified version) and click the media fire link in the desc. It's the same file I was going to send to you.
