I recently profiled a person involved in a series of particularly aggressive spam campaigns advertising crypto scams that involved so many fake new accounts that it briefly disrupted registration on some Mastodon communities.

Trend Micro has a new report out which states that the person I profiled was an affiliate of the "Impulse Team," a Russian-language moneymaking scheme that pays people to promote fake crypto investment platforms. Impulse Team has been operating since at least Sept. 2021.
