Today's spammer can become a real asset for the forum tomorrow.
In 10 years on Bitcointalk, I've seen that happen only once.
Who was that?
I forgot the name, it could have been before a name change. All I remember it was someone from the Nigerian local board who took my challenge to clean up his post history and stop spamming.
I thought it was you. I might be mistaken but you somewhere wrote about it that when you registered your intention was something else then later your interest grew for Bitcoin and the technology.
There was a user I can not remember his name. He was banned for spamming but later he earned a good name. I am not regular so I can't remember the name clearly. In fact, I don't know if I will recognize the user if I see him in a discussion.
