Do you think that a neutral tag would be more appropriate for this kind of Merit-abuse? You may be right, but certainly there should be some consequence to abusing the merit system.
Just left him neutral feedback. Seems somehow he got 1 merit last day. By considering his first mistake and user never joined any signature I feel neutral tag is appropriate for him. But if he annoy again for merit then reply on this thread and PM me, I will turn it on negative. Theymos is not much encourage to tag regarding merit issue if there is no clear evidence for trade or buy sell.
