if that is the evidence proving that all those accounts are mine, sorry but I really think those are not acceptable evidence for proof. You should have proof that those accounts created them myself or that at least they come from the same IP. [...]
Yeah, about that... there is a teeny weeny details that
igeble07 --or dare I say... you?-- forgot to omit: his email info. I have the archive
here and
here, but unfortunately web archiver can only log in as a guest on this forum --duhh-- and thus, the said information is protected by the forum. So, a screenshot should do. I've deliberately mark the forum timestamp, just to... add a little eligibility of the evidence.

About why an account who wrote a trust feedback in Japanese characters --I think it's hiragana, but I'm not a Japanese expert here-- actually registered under an italian email address, or if I may turn the situation, "why an italian registered email address wrote a feedback in Japanese instead of their own language?", is beyond my comprehension. I can only wonder if this is the same reason with uhh... certain someone who uses google translate to speak German.
But this is where things getting more interesting. You see, the email address used by igeble07 came from
reboldimario[dot]it, the same detail for contact info also listed
officially by reboldimario[dot]it, so it's kinda safe to say igeble07 really works on that company and have access to their email.

Now, it's been established
here that
metalcecco real name is
Francesco Reboldi, and combing through the site, I found
Francesco!

I don't know what's your opinion about this, but I personally think it is a good enough evidence to say that igeble07 at least works for you, if they're not you yourself.
As for
Ylli, (un)fortunately he hide his email address from public, but seeing how: (1) he wrote in Italian, (2) his account was created only to write the feedback and gone inactive right after, with a, (3)creation date that's awfully close to igeble07, and how (4) above evidences heavily implies that igeble07 is related to you and (5) metalcecco is you writing a very positive and supportive feedback to yourself in way that took pretense that they're two different people, would it be too far fetched to think that he is also you, err... I mean your employee?
