Like it was on Bitmixer campaign earlier. Users enrolls automatically and starts to spam without any control.
You don't have to go that far, looking at you own signature space already provides an example.
And I would say that some campaign managers' first language isn't English, but they write it pretty well.
So if english isn't my first language and I still am abled to write posts in a way that doesn't make native speakers start bleeding from their eyes,
am I really that wrong for expecting the same from users I am going to pay while writing posts on this forum?

No, that's exactly what I'm saying. Campaign managers should absolutely expect posts to be comprehensible. Some English is broken, but some people shouldn't even attempt it. And the Google translate thing just doesn't work. I think you and a lot of the other managers do a good job of weeding out the shitposters. I've seen you guys reject a lot of applicants, and I'm happy to see that. And as I said, I don't have a problem with the English skills of the campaign managers. They aren't the ones who are flooding this forum with shit.
