I noticed few post deserve merit, but once I visit their post history there are only bounty report and online post. So it's discourage me for send merit to them. I don't know what is problem if you delete your spam post, and participate on constructive discussion. Most of seniors are visiting post history before send merit to demoted newbie and also I think it should be.
I must confess, am guilty of this. My first posts on this forum were either to meet bounty requirements or to report bounty tasks. I saw them serving a purpose even though they were not constructive or useful.
Once a while I still look at my previous posts and see how evolving I have become; from a junk poster to a more constructive writer.
What I believe is history should not repeat itself. However such history should be seen as part of personal development rather than a basis for awarding merits.
As members become better users, merit will follow irrespective of any history.
