I'm not sure how safe Hola is, there are reports that it's a botnet. Basically your IP will be uses for DDOS attacks and spamming.
I've used it for around 2 years without any issue.
I imagine these users who have reported have other Spyware/Malware going on that makes it's way into Hola.
Can't be that bad it the Apple and Android stores are hosting it.
