Telemetry is cheap in the scheme of broadcast expenses.
If the station is operating on a shoestring budget, you have at least one human who cares that the revenue-generating operations (broadcast signal) are happening.
Similarly that person would notice the change in power expenses.
Even in the lowest-tech, least-compliant of stations, someone would notice an antenna and/or tower loss within a day. This reads like a case of severe neglect, almost certainly intentional, and possibly fraudulent.
