I dunno I could see where it might work to tamp down the hit and run trolls, but I don’t necessarily think it would work otherwise. BB has done a shockingly good job of fostering a nice discussion up in here so far.
I occasionally comment in a few other places that use policies like this. Hiding comments from new posters till certain goal posts are met, holding them back till they’re moderated, up vote/down vote etc. And it doesn’t ever seem to have the intended effect. Those comment sections are still rats nests, full of people trolling or being generally awful. I get the feeling that the hoops you have to jump through just scare off or frustrate the sensible people. Their comments don’t even pop up until the conversations moved on. Meanwhile any troll/awful person who manages to get them selves established sort of gets the stamp of approval to make a mess of things.
Here we’re all pretty good at shouting down the mal-actors, the mods are active and fearsome. But if I get grouchy and make an ass of myself I don’t get eaten by the bbs system, I have a chance to apologize and continue in good faith.
That said I have been generally avoiding discussions on certain hot button issues due to the greater than usual occurrence of vitriolic asshattery. It seems kind of sequestered to those areas, but maybe caution of some sort is advised to keep that from becoming the norm.
