Sigh, many people join this forum just to do bounty campaigns.
They spammed posts to reach Jr.Member rank - then continue spammed for Signatures campaign.
But too many spam posts lower the quality of the forum. That's why they make it harder (just a little bit) to reach Jr. Member rank.
If you want to do Signature again, try to contribute something good to the community, many people here are very generous with excellent newbies.

My English is not good, tried to help people but didn't know how to describe, so I'm fine with Newbie rank
