If you have given Sc03 task then you must be very careful and must investigate that either user has published his achivement 1 task earlier or not.
You can see that here achievement 1 task was verified by @ngoenyi and after verification of his achievement 1 task my job was to check jamesabby's achievement 2 task and verifiy it.

you can check @jamesabby achievement 1 task was 2 months old but again you people didn't check that user again 26 days ago published achievement 1 task and again @tarpan curated it

And that isn't over yet again that user published achievement 1 task about 13 days ago and again @tarpan curated, can't you see all that ????
Curators aren't able to see it that same user is publishing achievement 1 task again and again and curators are upvoting that user again and again.
How strange !
