I put into practice what I preached about preventing image leeching. Within the first 48 hours I got literally hundreds of email notifications from the logger I installed giving me URLs where I can find copies of my articles pasted word for word, including links to my images. I was also able to identify a number of sites owned by people who had taken the trouble to translate my articles into other languages (but were still leeching my images).
The first group of people (the copy/pasters) deserve nothing but contempt. I make it quite clear on this site that you may not copy and paste my copyrighted content. These people are simply law breakers - regardless of where they reside or host their shoddy, lazily put together excuses for technical sites, often festooned with advertising. Some of my articles take quite a bit of time to put together, and these criminals are making money from advertisers off my efforts. I don't care if you put a paltry link to my original article on your pages. You do not have my permission to plagiarise my content. Let me make myself quite clear - you are thieves!
However, if you are a translater, I don't mind you linking to my images. There is no way that I can translate my articles into Arabic, Urdu, Chinese, Korean etc. Consequently, I consider what you do a service. If you feel my articles are worthy of being shared among other developers who would prefer to have the concepts explained in their own language, that's fine by me. All I ask is that you let me know so that I can add you to my Approved Referers list, and link to your translated version of my articles. Use the Contact form on this site to provide me with the url of your translation and the language it's in (I can't always tell, you see...). I have already added some sites, so their readers won't be met with the alternative image my RouteHandler sends.
