Exactly, they're hoping to get some merits for their post and be launched into bounty hunting right away. When it doesn't work out as planned, they're off again.
Because the users here are very friendly to newbie and alt accounts tend to use the opportunity to get some merits. However, we cannot judge them also base on my experience I had created an account here before but I forgot the password so I was not able to open it until now. Then I create new and now been using it since then with high activity already. Been active in the forum for a while but my rank still in member. I was a shit poster and that says it all why I am still having low rank account. Well, I did not regret at least I earn merits recently and that is the good thing that I have been receiving and doing here in the forum.
