You don't have tangible evidence. In what way is it evidence? You're talking about different IP addresses, which are ridiculously easy to fake.
By fake I assume you're referring to proxying because IP spoofing is a whole other story.
As I mentioned before, there are different types of IPs. Those that are home connections, web servers and ones owned by cooperations for exclusive use by their employees.
When people use a proxy, it's almost always a web server. From what I can remember, Daisy only ever had an IP from a home connection. So if she was actually using that as a proxy, it's probably because she had a friend in another country who was using their home connection as a server and giving her special access. I just don't see it.
I then came across an IP that EJ uses which is for exclusive use to employees of a particular non-IT related company and that puts her in another country than Daisy.
So I'm not saying I have strong evidence but when it's weighed up against your evidence, which is purely posting style, I think mine is a little stronger.
