What can I do more to recover my trust?
First, it is very unlikely your negative trust will be removed now. Your actions caused you to get negative trust, and your words say you won't do it again.
Actions speak louder than words!
What you need to do is ignore the trust, and continue in the forum as a helpful contributing member. You may not be able to join a signature campaign, but that doesn't stop you from discussing and contributing.
After at least a couple months have passed, try PMing Hilariousandco and asking him for a second chance.
He didn't become a senior mod on this forum by being unreasonable. Good luck!
Once again thank you for your answers I really appreciate it.
I will try to be active as before but believe me I am filling like a criminal now.
I'm disappointed that other user used this avatar few days longer and nobody tagged him even after I have pointed this out in PM and this thread. I thought we have the same rules for everyone here on Bitcointalk.
Still, I think that warning will be enough in mine case. Especially when nobody was harmed. I don't want to teach high-rank members or moderators but I have to say that they should take into consideration many factors before issuing negative trust.
This is easy to destroy an account for which I have worked for five years with no problems or warnings.
