On March 12, it was reported that online data visualization platform Bubblemaps issued an article on the X platform to disclose the detection of witches in BMT airdrops, revealing that 30% of the rankings were robots trying to use airdrops, which had been identified and cleared through cluster analysis. Bubblemaps added that they should have received a BMT reward of $20,000, but the addresses were linked to each other through SOL transfers and their app activities were extremely frequent, showing non-human behavioral characteristics.
