These merits are shareable but some of the DTs are giving redtrusts because of another abuse created by the new merit system.
how are you going to rank up?if someone intended to give you a lot of merits,would it be called abuse?for example i have 10 hero accounts and i want you to get red trust i can simply give you 50merits at once and report you to these DTs,isnt that funny?
That is a genuine concern that I saw some others raising as well and there was no answer from an authority here about it. It is very much possible and hard to spot. May be they need to check in other aspects like past interactions in accounts before giving that negative trust.
So far as the selling of merit points is concerned even if they sell they will get exhausted of Smerits very soon. These will be mainly in hands of merit sources and i hope that the admin selects them carefully.
