Dealing with Unwanted Phone Calls Advice
You got some unwanted phone ranging from telemarketers to evil threatening of evil. Okay! It sucks; well, you got to let someone know about it, particularly, the proper authorities. May God forbid you from picking up or calling back, lest you were tempted to damnation!!!

For telemarketing issues, you go here (but I highly recommend this method!), https://www.donotcall.gov/ (.gov site requires state-of-the-art tech equipment, please use a [somewhat] recently built computer client/web_browser).
Registering your home/mobile phone number should prevent most telemarketers to call your number for 31 days.

To report the offending number, you go here, https://complaints.donotcall.gov/complaint/complaintcheck.aspx.
Complain about that fucking number and its fucking nature. Authorities should pick up the complaint soon. However, this seems to ring true for telemarketing/recorded calls. If the number is one hell of a trip like the witch hunt or red scare, okay, report that shit to the cops! This is something I need to do.

Okay, how to prevent these God damned numbers to ever reach yours without depriving your calling privileges?
If you have a mobile phone, try to reach the "Call Settings" option, "Call Barring" option, "Incoming Calls" option, "All Calls Except SIM Incoming" option, and then activate that option. This option prevents any calls other than those listed on your SIM card, to call your number.
This is great; however, if you want to go to a greater extent, you can do the same to outgoing calls. That way, you can only call the numbers listed on your SIM card. You don't have to worry about accidentally calling a unwanted number as a trap.
To bypass the ingoing/outgoing call block, just copy the number information to your SIM card.
If you have a home phone, then I suggest to contact your telephone service provide for the instructions.

Still, your voicemail can let people know that your number exists, even worse to harass! This is pretty fucked up. I honestly do not know how to stop this, but contacting your telephone service provider does come in handy (hell, I panicked until I got though the entire ordeal). I tried to control call forwarding or voicemail greeting, but I figure the call log would still be that evil stalking-like reference, even though you are willing to retaliate on your own terms. The only way to actually retaliate is to find the offending caller, and kill that son of a bitch!

Still, you will need to report the manhunt calls to the police or you're dead.
Fuck, I have one right going for me throat!
In that case, I would direct this issue to the telephone service provider and law enforcement. Yes, we do have the complaint of donotcall, but one isn't enough when you are faced with a threat of an unknown nature, possibly, in many different forms or agents. I hate those fucking things, them and their damned philosophy. Hopefully, a (maybe a trap) solution is being made that way, usually by the telephone service provider.

Great news, maybe? I am tempted to try TrapCall and hopefully, it better protects privacy (blocks number) and facilitates in better security response (records call). Maybe for the next time around.

Oh yeah, smartphones don't seem to have these features installed for some reason. At least mines was the example.
