At the same moment when 0.8.15 came out and I heard about Whatsapp banning numbers I paid 1$ for one year and downloaded 0.8.15. I've no intension to change to android whatsapp since it sucks especially with notifications until I get banned for the first time..
I'm gona continue using mitäkuuluu till the end and I've donated couple times and will continue to do so.
And if it matters I registered by using Mitäkuuluu.
I know it's a long shot but could Whatsapp just simply observe mitäkuuluu users' statuses "I love mitäkuuluu" to spot them and bann them?
