I see the reasonless policy as liable to being expoloited by people who simply don't want their views countered by x, y or z. While I think this is in line with the style of a moderated comments section of a publication, for example, I think it goes against the spirit of forums.
But a lot of the things I like about forums, like making a thread called "Is Guess Who a Right-Wing Radical?" would be a no-go under these policies since they now go against contemporary sensitivities, apparently.
Re: social distancing requests. I would not ask for evidence, or start up a whole trial to determine the validity of a claim. I would simply expect the claim to be based on decidedly unsportsmanlike behavior on the forum, or even bad behavior off the forum. If someone has a claim of harassment that cannot be proven, who cares, I would take it as valid. I donot see the need to investigate. I would also make these "restraining orders" publicly accessible knowledge, albeit not the reasons for them (you're probably going to disagree with that too, lol). Edit: if you've set up a restraining order against 10 people, as a forum member I'd love to know that.
Ultimately these differences are not terribly important to me. I'm not going to pretend to agree with them but neither are they going to discourage my participation. I'll just see it as regrettable and move on, hoping it's going to be okay.
