How realistic is it for us to ask someone who spends just a couple hours here every week browsing through the marketplace to create a fully customized trust list?
Well you've been around quite a while and you've interacted with a number of members here--at least through posts, which I remember reading. Surely there must be some members you'd trust enough to put them on your custom list, even if you wouldn't necessarily trust them with your life or large sums of money. It's not like a custom trust list has to be extensive.
For new members, I can see that this could be an issue when you don't even know who anyone is. But it's not the end of the world if they just use a suggested list temporarily. They might not even care about the trust system at all.
Its called use another forum/ subreddit. If you don't like it. no one is forcing you to stay here
Now, now, he was asking a genuine question although I don't think OP seriously would have a problem creating his own trust list. I think he's been a member here long enough to know at least who NOT to trust and probably has a short list of candidates for inclusions in his own list.
