They were not really an amount that was anywhere near being significant in the overall picture, but some of the cases were clear-cut enough to get the Admin’s attention, leading to the TXs to be deleted or countered in a few cases.
Deleted: The sMerit TX was deleted and the counters readjusted.
Countered: A Negative amount TX was issued from user "0" (a virtual forum account used for these porposed, with Id 0 on the sMerit TXs).
It's nice to know that there could be an error actually. Having the system fully automated gave me the impression of a some worth perfect system. Well, its not perfect any way and Theymos surely did put it out in the clear cut situation of sent merit as described in the last referenced link as on the first page. Which ever way, yiu did open my eyes to this and I can say, I am aware now. Thanks.
