I deactivated Keepalive just in case. If I get blocked I won't be able to register again. The phone number I am using is not mine any more (is an alias from Fonyou service, but they closed). Moreover, if I get blocked, probably I won't use Whatsapp more. I won't give them my real phone number.

I hope kontalk guys finish soon their client (now in betas) and get promotioned by free software community... Is almost just xmpp, is all open protocol, is all free (libre) software, have syndicated servers, OTR encryption...
