I'm putting my response in an answer here as replying in the comments is leading to a lengthy chain.
Contacting investors/directly directly is a bad idea. It may even be considered harassment. Why? Let's look at it this way;
By definition, in this question, there have already been 5 attempts to establish dialog
- Meta
- A Petition
- Phone
- Contact Form
If these don't make it far enough up the chain to be seen by the investors/directors, this is likely by design. They either don't want to see it, or they can't do anything about it if they do (consider they may just be financial backers). Even if they can, it's likely that it would take more than one. Circumventing this by contacting them directly when it hasn't been requested is unsolicited contact.
Aside from the above, what impact do you suppose this would have? If the 5 previous attempts have been ignored / not answered to satisfaction, there isn't likely to be a more favorable outcome contacting them directly.
It also depends what you hope would happen. Would you want them to pull backing? Interface with the community? What would be the end goal?
