It is really usefull to listen to the rest of the community. Your words made me reconsider the matter.

Strangely, I am the other way around.
I refuse to do general unpaid translation tests for agencies. If they wish to check my work they can ask for references, a sample of previous work or they can pay me to do their test.
However, for project-specific tests, provided I am positive it isn't a scam to get a free translation, I am normally quite happy to do them. If you get the job, you are then paid for the test
I'm not sure if I have an officially formulated philosophy on this matter - just how I've always done it.
