I think it should not be acceptable to make a challenge by a non-verified account. Ultimately we must have transparency on who are the watchers. There needs to be social barriers as well as cost barriers for challenging people’s submissions. There are people that are being challenged that are clearly human. Any human can see that but people can hide behind anonymity at the moment in the challenge process. To create unnecessary costs for people who don’t necessarily have the money to pay for failed submissions is not human.
