The recent addition of the merit system along with the abuse of the new additions to DT2 will make it much harder for those tagged for invalid reasons to gain merit.
Im not sure about you but id think twice about awarding merit to someone with negative trust.
The merit system seems good for new members and removing the low level posts and single sentence posts, but from the looks of it lots of older members who have contributed to these forums are being left behind and forgotten about while they try to address the problem of spam.
