As I was mentioning, it was either, as you just mentioned, through the RCMP, or they could also use internal information using their software, their algorithm, to see whether there were any activities related to these blockades. However, we're not privy to what they found. They would vet the information. I'm sure if they had questions, they could have had maybe contact with the RCMP, and the decision was theirs to make if they wanted to freeze the account.
