WhatsApp spam messages are very annoying

WhatsApp is a convenient tool, but it becomes very annoying as more and more companies use it as an advertising tools. Many unwanted messages and advertisements come from unknown numbers sending to me, WITHOUT MY CONSENT. 

There are three things that I HATE most with WhatsApp
- Anyone can send me message WITHOUT MY CONSENT. They can just send message without knowing who you are.
- Anyone can  add me to a group WITHOUT MY CONSENT. They only need to input my number in to the group and can force me to join the group and send me message.
- I can ONLY BLOCK a sender AFTER RECEIVING THE UNWANTED MESSAGE

These makes WhatsApp a GOOD channel for advertisement and spams. Just purchase a charge card, add a bunch of numbers sequentially, send the messages out then dispose the card. You have no way to escape from these spams and it is useless to block these sender as they are using charge card and will only use once.

Why WhatsApp cannot introduce some measures on the spam controls? Why doesn't WhatsApp give us a way to accept sender before they can send a message to us?

There is a simple way that WhatsApp can help us, just give us two options:
- ONLY ACCEPT MESSAGES FROM MY CONTACT LIST
- ONLY JOIN A GROUP WITH MY EXPLICIT ACCEPTANCE

If users like me who don't like unsolicited messages, just enabled these options. For others, they may disable these options and behaved as before.

How to set XE8 FD Explorer ini file Setting location

In XE8, you can find that the ini file setting location has been set as following (you can find this in the FireDAC Explorer):

Connection definition file = C:\Windows\FDConnectionDefs.ini and 
Driver configuration file = C:\Windows\FDDrivers.ini

The problem is C:\Windows usually not allow for file write and that cause a problem, I CANNOT create any connection definitions.

These settings are readonly, though there is a checkbox for you to set default.

The only way that I can find to modify these location is by REGEDIT.

You can find the settings in HKEY_CURRENT_USER\Software\Embarcadero\FireDAC. Just modify the value for ConnectionDefFile and DriverFile accordingly and you will be able to save the settings.
