On Telegram there is a little something called Settings. If you click on Privacy and Security, you can control who can call you. But I know. The Russian government and a private company are plotting to find you in Canada. A hard-knock life.
Why would I care about the Russian government? I had good business with them before Canada sanctioned them. I just made sure to warn they get info from it.
Also, the private company loves and needs me, its random commies that dont like my opinions that call to make problems for me, except they call and find no victory because I refuse to exist.
Also, if you know anything about Russians, if it becomes in anyway beneficial to use your info for their ends in the future they will. So I trust them about a hundred or two more times over than facebook, and am not giving them my number either.
