You don't see? Do I need it to spell it out AGAIN?
Running a site creates costs.
Running a forum creates costs.
You have to cover them.
People who block ads create costs but act to prevent creating income.
You actively(!), willfully(!) harm the site.
You don't want to pay nor ads? You are free to go AND NOT USE THE INTERNET. I am sure there will be many, many free, big sites left if everybody acts like you. Exactly one:
a site made by a parasite whining around that only paysites are left.
There is no such thing as a free meal.
