This unfortunately is a bane in the digital world. Where bits and bytes can easily be copied and redistributed. Such is the case with MODS and just about any code. I think we can agree the rampant distribution of music via the mp3 format has changed the dynamics of the music business.

In a similar way mods are being copied, slapped with someone else's name and then resold. It was brought out however, how can you prove it was your code or "answer" to the problem to begin with? Most problems see more will have a similar set of solutions or at least a similar framework. In this industry, you really can't own an answer. But you can have it attributed to you.

The software, music and movie industry suffers from the benefit and bane of digitalness. I'm not surprised it happens to mods as well.
