NoNewTaleToTell: Clickworker is available in the EU I believe, at least I know for sure that it's available in Germany because it's a German company. Appen and mTurk I'm not too sure about. There are more legitimate microjob sites too, those were just the first three that popped up in my head.
I tried to sign up for mTurk and they sent this:

Clickworker has Russia in the drop-down menu, but the form changes depending on which country I pick and specifically the Russian form is built in a way which prevents me from filling it in correctly. I *can* lie like a rug and pick the US instead, but they will probably ban me for it.
Appen I have no idea how to sign up for.
