Today, I came across an article listing ways to block robocalls (Link in the references section). 

When it comes to these kinds of articles, with due respect to the writer, we need to understand that theory need not align with practice. 

For example, one of the suggestions is to register in the site. 

Please see the below email:

to me
Thank you for registering your phone number with the National Do Not Call Registry. 
You successfully registered your phone number ending in #### on March 26, 2008. 
Most telemarketers will be required to stop calling you 31 days from your registration date.

Visit  to register another number or file a complaint 
against someone violating the Registry.


I have been receiving telemarketer calls even after more than 10 years since this registration.

Without going into all the details, I have taken many steps at least on the personal front to address issues, such as spam calls, spam letters/mails, spam emails, scams and more, and most of the tools out there needs significant improvement. Otherwise, we would not be seeing the same issues even after two decades, in spite of supposedly having better technologies and tools.
You might ask me why don't we file a complaint?
Then, we have to run behind those complaints and waste time in the process. For that matter, I might have submitted some for other similar such issues in the past. 
When it has become all about making the money the fastest time possible with an ecosystem that appears to be in place solely for that purpose, the person who brings up would be at the losing end. I guess wisdom with experience. 
Does it mean that we have to let go of these incidents?

One way is to improve awareness, even amongst those who spread those robocalls. They have to understand that this kind of robocalls would make even those individuals reluctant to answer calls, and might end up missing important calls (it could be a call from a loved one or a call from a doctor) in the process.

Please understand that these would not happen if there were not a financial engine that is funding and backing such spam systems. 

We are also looking into developing reliable solutions from our consulting unit, Val-U-Pro Consulting Group, LLC for this purpose, which includes spreading awareness.
