.. free VPN be it Opera or more dubious not really to be trusted. Might be OK to access region locked content e.g. US media from UK (big regional release date differences on film / TV - silly (IMHO) as it encourages the keenest fans (who must see it ASAP) to pirate)
Dont ever do anything that involves exposing "proper" credentials with them, just use if as a region block unlock and ensure you run it in a VM in case it tries any nasties.
.Finding a VPN you can trust is non trivial (there's always the set up a box in a different country and roll your own VPN for the truly paranoid)
