At least most of them really deserved those merits, you think is easy burning time to carve those things?
It was certainly not easy for some, because we can see from the examples that some participated with more accounts and therefore had a lot more work to do with carving more than one pumpkin. In addition, it is not about stone or wood that is processed, but about an ordinary pumpkin.
A very simple solution for all future contests is to make it impossible to give merit in such threads and then we will not have the need to discuss such things.
Yeah absolutely.
And in addition, I think next time there should be some restrictions or level of account that may be eligible participates, but haven seen that there are more people using multiple accounts to participate or sharing merits among themselves can be panelized and phish out quickly.
Somehow at @Igebotz was right, seeing an account filled with bounty post or reports doesn't deserved any merits. Although we give without viewing most of their profile.
I would love the next contest not be open for bounty account and newly created account may not be eligible to participate, there should be some sets of ranges to participate in the contest imo.
. But the fact that the behavior of some accounts seems suspicious is true. I can tell that this farm betrays itself with its consistent behavior, which seems to be expected, and in the end, everyone who tries to be too cunning here will be exposed.
