Longer story: WMFR just received an OTRS message from a WLM competitor who discovered that someone is wrongly taking credits for its WLM photos (and other WLM files and other files from Commons apparently) on the fineartamerica website. This competitor send a mail to this website and asked if WMFR can help in any way.

So now, I'm sending you this mail to know whether you had to deal with things like this or if you have any ideas of what should be done.
