Well, that's only one of the apparent problems with Hola.hola collects and sells userdata , so preferably do not use it.
Another one is the following
"They send traffic of strangers through your internet connection
Hola is a "peer-to-peer" VPN. This may sound nice, but what it actually means is that other people browse the web through your internet connection. To a website, it seems like it's you browsing the site.
Perhaps that doesn't seem bad to you. However, imagine that somebody uploaded child pornography through your connection, for example. To everybody else, it seems as if it was your computer that did it, and you can't really prove otherwise."

Adios, Hola! - Why you should immediately uninstall Hola
After reading all that, I'm not interested in Hola. I have used Zenmate and DotVPN in the past, and they both worked fine for what I wanted.
