I would then recommend you make a new thread and ask Bitcoin experts if those two addresses are part of the same wallet and what that actually means, and then you should be able to determine for yourself how likely it is that they are the same person. To me its pretty clear that these accounts are the same person however you need to be able to understand the evidence to determine that for yourself. I don't see how you can say it isn't strong evidence when you clearly do not understand it.

As you can see those 3 addresses are in the same wallet.

If you look at the above timeline then you will see that poeEDgar signed a message from his address which shows the addresses are not part of some kind of service or website.
