What's your take on this? Can they change or is a spammer always a spammer for life?
I think they have fair chance for that. I just remembered when I am just a bounty joiner on altcoin campaign and my post are literally consist of social links for quota weekly. After 2yrs from doing that, change my perspective and style then able to contribute some on forum leads to ranking up. So based on experience, theres a chance if they really wanted to change and focus on the improvement of themselves.
