Once is happenstance. Twice is coincidence. Three times is enemy action.
In January, I published an article describing how a company called Pixsy sent me repeated legal threats in a bid to get me to pay $600 for a Creative Commons imageI’d used. Pixsy falsely claimed that I had violated the Creative Commons license by failing to correctly attribute it to its creator, the photographer Nenad Stojkovic. After I challenged them on this, they apologized and withdrew the threats, but refused to answer any of my questions about how this happened or how their business operates (Stojkovic also failed to answer multiple messages seeking clarification).
