I guess yes because I've active in this forum for a year and never saw this cheat before.
It's not a new occurrence actually, just that this case managed to fall between the cracks since the payout days for both campaigns are different so the cheater could switch between Duelbits (Tuesday) and BCR (Thursday)
With so many members to handle, campaign managers might find it difficult if a member makes the switch before the tally.
I don’t think this happened as a result of the number of campaign participants, I think this case flew under the radar for so long because of his posting habit, the account mostly made posts in gambling board and Pakistani local board making it difficult for the community to notice the frequent changes in avatar and signature code.
