There are many reasons for that.
Especially as SocialMeetPlace.com is a Social network which is built by Users for Users.
Most important is that there are mot all that Limitations like you find it on FB.
Not in Number of Friends allowed to have and also not in adding new Friends.
It is always annoying if People get blocked for adding Friends, just as they want to add People who are not known in real Life.
There is no Sense behind that as the Reason for joining a Social Network is mostly to find new Friends.
Next Reason is that Data will not be saved and used for Marketing Campaigns if a User cancel his Membership, like it is known from the biggest Social Network known now.
And Least but not Last is that SocialMeetplace.com have many more Features than any other Social Network.
If someone is supporting this Campaign he is supporting the building of the best Social Network for Future.
Every Support is appreciated
