I would pay cash for access to a social site that bans all US politics, the astroturfing associated with it is simply unbearable.

For a short time I was a part of a small site that banned politics.

It was fine, people talked about work, personal stuff, travel, until one person posted about their disappointment that their state was limiting various services or rights to gay people. For them this meant their rights were in question and they were understandably upset.

Immediately some folks cried politics and that they shouldn’t post about that sort of thing.

To the user posting it it was about their life…

I don’t think “no politics” rules really make much sense. For someone it’s more than politics, and IMO because a topic is touched by politicians or government shouldn’t make it disallowed.

Wouldn't that be almost impossible?. Politics affects our lives every day. Your comment suggests that you believe it doesn't affect yours.

Why do you think people will stop at politics?

Erm, Brexit, anyone?

You thinking that astroturfing only happens for US politics is dangerously naive.
