The forum itself is a bit wonky if you noticed, it's a bit off to the left side which is what we are currently trying to fix as we are editing things around a bit.
The reason the adblocker removal is apparent now is because the login page, as you might've guessed, is full of ads when you log in. There were no ads on the forum, but there were tons of ads lingering when typing in the forms to the login page. Many people have complained about getting viruses or ads that are harmful and malicious, so we removed them from the login page and brought them onto the forum, which is why it now tells you to disable adblock to access the forum and login.
It's a much safer alternative that likely getting harmful ads or malware from the login page, which we want to avoid.
