Cryptocurrency mining violates the law?

Question

Law in IT

I have been mining for a long time, but not professionally, purely on Morozhenko).
Not so long ago I was asked to assemble a miner, I collected it, they gave me money and so on 2 times. Then I changed
my miner to another and decided to sell the old ones (RasPi and hedgehogs + RasPi and USB whistles)
, I posted an ad on Avito, and the moderators blocked it for violating the laws of the Russian Federation.

Answer 1

I think they have such a preventive measure, so that later they would not get into the register.

Answer 2

No bans as long as possible
