I receive those every day. Actually few every day, if I bother to look into spam folder - and if not, they help my email hosting to improve spam filters.
Not an anon because there is nothing to be ashamed of since the "facts stated" are obviously entirely made up. Sometimes I am tempted to try to hack these back (tracing bitcoin wallet activity is plausible, there might be also interesting traces in email header) but can't be bothered. Someone will, eventually.
