Be a member on any invite only torrent tracker

This is the scenario: You search for your favorite game.You find it on torrent only prive site. You try to register and you can't because maximum users limit have been reached and you can only be a member by invite.
Here is a tutorial how to bypass this

You need firefox first.
Now you need two plugins for Firefox, the Check4Change and the AutoFormer

This guide tried on two trackers, blackcat games and another tracker.
Blackcats-Games is the best dedicated games torrent tracker out there. It tracks several thousand windows and console games. Obviously, it is not easy to get into and the tracker had signups closed for a long time and later the admins decided to close the invite based signups too. Now here is the good news; although you may not notice it, the Blackcats-Games is accepting new signups. You just have to be there at the right time.
You can try on any tracker you want, or try on any other site.I don't know if this method works on anything else.

Please note, you must provide your real (from your ISP) email. Blackcats will not accept popular free email addresses. If you have an ISP provided address, use it. If you don't, gawab.com mail seems to work fine.

Okey, go to blackcat games and hit on signup.
Normally you will receive this messange:



Now highlight the message and right click on it. Select check4change and then custom.



Enter 3 seconds in the "Refresh and check every.." field under "Check Interval". Also tick "Dont refresh while viewing page" button. We need the last check to avoid reload the page when you are on reg form.

Now, go to another tab and let the plugin do its job. Note, you must have the tracker's tab into backgroung, or else check4change will not reload the page.

Check4Change will now refresh the page every 3 seconds to detect any changes. Within 10 mins it will detect the signup form being loaded and notify you. Now take your time and fill each and every field (Except the captcha) carefully. Double check everything and make sure you tick everything.

Before you click submit, Go to FireFox Edit menu-->Autoformer--> click "save all fields". Now press submit. You will be greeted with "Max user limit reached' message again. Do not worry this is normal if you bypass the 30sec limit Blackcats' has.
If you can write fast, you don't need the autoformer step. I registered without it. So, some users may need time to fill the register form.
