Here's the post that caught my attention (edited for brevity and warrior compliance):
Be careful when you are hiring outsourcers. I tried twice and got burnt badly. The guys, to beat copyscape sent me content where O was replace with 0 (zero) and I couldn't detect it. When I spotted it, and sent it back, they said it was an error. Guess what they did next. They used the Greek O in MS Word, so that it would pass copyscape. |
This, I couldn't detect, but a friend of mine did, with his custom software. When we cleared the Greek O, and then ran it on copyscape, it was plagiarized entirely from another authority site.
If you know another way to detect non-engllish characters, please post your suggestion.
If you've been burned some other way, please post your experience to help others.
