Well its not that hard to make this observation when you have seen what I have seen in SL over the years of logging in & playing.
I am not really here to judge countries based on this, be racist, or say that a country is bad because I am not, and I am not going to make the claim that no bots come from the U.S because doing such would not be true.
However what I am saying is that Over the years of playing SL my obeservations I have noticed that most the bots I run into have come from foreign countries, and its not hard to tell because they are speaking it in text, and some of them over the mic, and I know what language it is even verified it through google translate, and not only this but in SL is only part of it. I had the person on my contacts list outside of Second Life and I saw they were also from a foreign country as well.
When I checked the Host of the website I talk about which keeps changing I noticed that the site was hosted in Germany by a germany provider checked it by WHOIS multiple times.
If you actually make a throw away account of course assuming you are willing to risk the security or use a different computer you could always go create some of yoru own content and leak it as if you are a griefer making a share and get in as a Spy, and then you can find out easily where a lot of these griefers come from the people who BlackMail others with things like You do this or I am going to Do this and so on. Although there is no need because over the years I have kept a very good eye on quite a few goons winks, and its finally come to the point where I have absolutely had it, and so have the people I know in SL who wish to remain anonymous they have gone too far.
While I have mentioned foreign countries here this was just an observation of things I have seen over the years, you see most botting griefers like to hang around Welcome Areas, RolePlay areas like "GOR" which is a big place so they can clone avatars this is where I usually find the foreign botters.
However with saying this Do you all remember the Voice Exploit,where it was possible to obtain peoples IP addresses and geolocate them? Yes thats right I used this exploit on many of the little kiddies hanging around the welcome area years ago its not illegal to do just monitoring my own packets off my network card, and you see I discovered that quite a few of these IP's were likely Kids with Girefer accounts, and I will say they were from the U.S because I tracked back their IP, and they were not on a Proxy or VPN either I ran multiple checks. They have the nerve to hang around welcome areas and brag about how they Copy Stuff, Laugh on the mic, and you think you can hide behind all your alts from someone like me think again, I am not stupid, and I am not someone who abuse things in fact this is the first time I have ever said anything about using this exploit and knowing this I am done I want to see these griefing kids gone.
http://www.iprcenter.gov/ I don't know what else to say other than I filed a long report here explaining the issue, and all the Hosts of the site I could find on google, I think that other merchants who hold intellectual property rights do the same thing especially when you know your work has been posted there the more who file the more chance hopefully it will get taken down and they will legally do something here about the Bot's, and finally justice will be served to the person who is running this service, and all of those making donations, as well as posting the content themselves.
Something needs to be done to save Second Life from this grief.
