I believe in @steemchiller 's Steemworld there is tool find abuse, but I am not sure how far it is possible to search or maybe to implement Blacklist into Steemworld, as everyone is using it. What do you think @steemchiller?

Because now it i sheading toward end of year 2 beg. of 3 years since split, the number of such Identity Frauds will be going up. The problem is due to many communities, even if one community banned user he can post in other and start with clean sheet.
