Why?
The reason for the suspension is related to Twitter’s “counterfeit policy.” The social media platform doesn’t list any concrete takedown requests but simply mentions the policy violation and the fact that its decision can’t be appealed.
“Your account has been permanently suspended due to a violation of Twitter policies, in particular the Counterfeiting Policy. This decision is not subject to appeal,” Twitter writes, translated from Russian.
