How do you know it's ARG and not AdultTime or a similar platform? Also, who says they have special treatment?
Even if it is ARG, they have every right to do so. We're a pirate site and what you are asking for is special treatment for yourself.
Just click on the REPORT button in the first post when you find dead links. That's all you have to do.
And if you are talking about links people post in the thread, many times people are posting links to file hosts that ARG is paying for so that their subscribers have access to the product they subscribe for. If that is the case, ARG owns those links and can do with them as they see fit.
Finally, if you actually have a legitimate complaint (you don't), open a
support ticket. Don't whine in the thread. You are well aware that threads are not monitored for the most part and only are reviewed when something is reported. You've been here long enough... And have had messages reported often enough to know how it works.
Edit: and even if you had a legitimate complaint, nothing stops creators from using a different email account, vpn to make a new account in a different name to see the links.
