There's been some discussion on how to maintain this thread. It's difficult to maintain as what some people want to see may be different from others. The mods also can't go through every account of every link posted.
Yes, a lot of these creators are members of some sort of management scheme, but sometimes there's a little bit of decent content here, or someone wants to buy some paid content and maybe share with the community.
The only blanket rule we've considered is maybe differentiating between "trial links (the long links)" and "free accounts/limited trials (link to profile that is free [sometimes for new users only])", which may at least cut down on some of these. I'll post a poll regarding this.
