or you have copied and pasted the post.
Yeah.. honestly I think it's not that horribly to give permanent ban.. anyway I can't do anything here, do you know I have chances for unban?or you have copied and pasted the post.
Anyway it was stupid mistake. It was a bounty, where is provided link to bitcointalk post. The task was "Answer any question", but by my mistake I thought it was "Ask any question" :/ so stupid.
