Character substitution to avoid copyscrape type programs has been around for many years. When WYSIWYG editors became available, the incidence of this content theft/infringing increased... those who work with hands-on html editors could spot this scam very quickly. With the rise of cut-and-paste webmastering this type of deceitful product worked more successfully. It was up to those purchasing content to make sure they get what they pay for, and most did not/do not make that effort.
Example of one of those "if you let me get away with it I'll keep on doing it" and "your deserve what you get if you don't make the effort to assure the product is suitable" kind of things.
As this is a Content forum, the best advice is to write your own content. Second best advice is to obtain content from known to be good sources. There is no third best advice that I know of.
