Warning: Stay away from sms.ac

I got a few invitations from people I know which lured me into joining although I was suspicious. I've now terminated my account and I suggest you do the same if you have joined them. The reason is that it's a truly disgusting company that sue people which posts not entirely positive comments about them. It looks like they are pretty agressive about getting people using their service. They are sending out invitations that looks like it's from you, but as far as I can tell, they are doing it more or less without asking you. Besides their questionable business practices, their website is not particularly impressive. It's slow, the design is confusing and it looks like it's optimized for Internet Explorer which I don't use.
