After telling you in this post that my account got blocked I want to add some information about the actions the let to this result.

After using our great WhatsUp client for more than a year I tried to set up a group to invite some friends for my brithday. The version I was using was 1.2.7. While initially creating the group I added 10 persons. Adding more was not allowed by the WhatsUp client. So instantly after I created the group I tried to add 2 more persons and BANG... I got banned.

It seems that we do something different in creating groups or adding persons than the original software.

I hope this information may help others to avoid the problem or to improve our WhatsApp client.

Best Regards,
SecretAgent
