Welcome to the Q&A Forum

As Mike has said, the fact that you are often linked to, and the content is translated, would put this far down my priority list as far as SEO goes, in that it's not going to hurt you (unless the site are extremely poor quality and linking to you a high number of times, which doesn't sound like the case here). I take it they're just lifting the content, not scraping the HTML, given that the content is translated. If they were taking the HTML, you can place the canonical tag in the source code and make it quite likely that they'll publish their version with a canonical tag, pointing to your site. From a legal point of view, you probably have good claim to go after this behaviour, which is up to you. This should not hurt your SEO, however.
