Every day about 60 new members register in Numista. There is not a great variation from one day to another, and there is a slight upward trend over time.
I was struck that there is one day, on August 5, 2019, that there were 400 new members. Four times the previous record in Numista history. When looking for what users they were, I have found that most are very similar: same name structure, English language, no country, no posts, no coins, no swaps. I think someone has created more than 300 clone users. It seems suspicious.
