I was banned last month. (Here is my profile:
https://bitcointalk.org/index.php?action=profile;u=86256).
I tried appealing the ban through email, but I got no response.
I am a member of this forum for the last 6½ years, and I think if someone wants to ban me then he should at least have the decency to tell me the reason for my ban.
Reasons of bans presented in Red message. Mostly spam or plagiarism. Did you get such ban message? Rule on plagiarism has become more flexible after the kick-off of recent banwave. If you can show that you are a constructive user and have good neteffects in the forum via your contributions, you might have chance to get reduced sentence from admins or global moderators. Chances become higher if you made very little plagiarism, and in such plagiarism, admins or global moderators don't see shady intention behind. Being here too long won't help you to get reduce sentence.
Mostly, @Veleor will come with proof (but he is not staff), and I think you should patiently wait for him.
