great idea. use the app tied to your passport and gosuslugi to make sure they know who is the genius when they detect it.

edit: didn't know they allow anything except belarus, cool... as long as you can anonymously register that number

I don't think they would care as long as you don't do something stupid that would show up on their dashboards. But if you're paranoid, you can use phone numbers from, for example, Armenia or Kazakhstan. There are 8 countries besides Russia whose numbers they allow.
