Even though I'm not native in English, I've been writing in the language for about 10 years, on a daily basis.
And I don't mean just phrases like "gg wp" if I'm playing a game. I'm talking about articles, ebooks, tutorials and guides. I know that I'm not skillful enough to write in perfect English, but I've realized that I'm good enough to express myself properly in most cases so I wouldn't care about a visit from this bot.
I would probably never upvote the comment and just ignore the comment most of the times. I seldom flag anything.
Thanks for your opinions. It's a type of a social experiment and as a business model I think it will have a tough time!
