serioz tho...
The best way to get rid of those precks (like ALL of them) is to NEVER answer the phone unless you KNOW who's calling.
I use my phone to take picture, transfer files and mixes, write down notes, to read e-mails, go on FB and such. I use it to mess with the cats when they're on the porch via the camera speaker. And once every few months, I use it to make a call. I hate phones (ironic considering that I've worked in call centres for so long). The only time I pick up the phone is when my wife is calling to say she's on her way back from work.
The rest of the time, I'll choose written over verbal communication every time.
I also figure that if anyone has anything important to say, they will leave a message.
That one morning, I got up to find 2 or 3 messages, telling me in a very aggressive tone that I was accused of tax evasion and that I needed to call back this number. Now, I hate to be threatened, especially before my morning cup of tea, so I figured that I needed a way to block those fellows.
Considering the number of calls that app blocked, it was not a bad idea. Plus, sometimes I'd see that I'd missed a call and look up the number on the internet, but now, Hiya does all the work for me - all incoming calls are not only screened but also identified and logged, whether by caller id or by call category (extortion, telemarketing, etc.) Time saver.
