Trusting Russians

One should be especially careful to avoid using any sounds produced by Russian uploaders, since they love changing license mid-flight. For example use Dmitry Urupin originally uploaded his sounds under public domain, but then changed the license to a proprietary one, disallowing any commercial use:

Ooops!

Remember: you can never trust Russians.

You know I'm a game developer, but I'm a programmer, therefore I can't draw. So I've tried to hire a few freelance artists in Ukraine. Several times. The dialogue was always in the form of:
Me: Hi, dear Ukrainian artist! I need a freelancer to draw some art for a video game. Expecting two-three small 256x256 artworks/month. The stuff you can do in an evening or during a coffee break.
Ukrainian: Yeah. I can do it. Here is my portfolio. Send me the description of what to draw.
Me: Good. Sent the project files to your email.
Ukrainian: Fine. I'll check them this evening.
Ukrainian (after a few days of silence): Sorry. Your files haven't arrived at my email.
Me: Strange... I've resent them. And here is a direct web link to a zip archive, in case something is wrong with your email.
Ukrainian: Ugh... well, I got them. Do you have PSD files for existing art?
Me: No. I don't have Photoshop, I'm a programmer, not an artist, and such professional art software costs a lot. And why do you need PSDs for existing art, when you're supposed to draw new art? The art in the project is solely for reference. I haven't archived PSDs.
Ukrainian: What happened to the artists who worked on your project before?
Me: Thats none of your business. But if you need to know, I never had any permanent artists on the project - they were freelancers, who got paid, and then I ceased working with them, because I don't want to deal with Russians anymore. Other art is royalty free stock art, which has no PSDs attached. Do you want money or not?
Ukrainian: I'm terrible sorry, but I can't work on this project, because of personal reasons...
Me: Great! I've just wasted my precious time on you, you piglet!

That exact dialogue happened several times, so I've to conclude that all Ukrainians are very unprofessional and lame, having this Asiatic mindset of a barbarian. Instead of drawing they prefer to go into fights about it. I'm yet to see a honest and hardworking Ukrainian, who can just do the work. Dealing with Ukrainians is wasting your time. Guess Ukrainians are no better than Russians. Since I had similar problems with Russian artists, who also asked about existing PSDs and previous artists. True subhumans.
