Whose representatives? Not mine, as I am connected to none of the mentioned companies :)
My point is simple, actually:
1) It does not matter where a company is located as long as
a) it is upfront about it
b) owner nationality corresponds with company nationality (place of incorporation), for reasons of legal accountability
2) It does not matter if a company hires highly qualified ESL writers as long as it is upfront about it
3) Legitimate companies should not throw mud at each other but need to work together to push out the scammers
In other words, were you a Vulcan and your company registered in a different galaxy, it would not matter as long as customers are given the relevant facts.
Our company is officially registered in GB (with all necessary Companies House documentation)
I found this rather curious. Why register in the UK if you are an American?
Now with regards to the `spamming IP' issue, I have a comment. A few months back, and for less than a week, we were linked to a spamming IP. Upon investigation, we discovered that it was the SEO company we hired. Of course, we fired them on the spot. The point here is simple - none of us are infallible but we should admit it when there is something wrong, investigate and correct. We should not come up with excuses.
