"Cleaning" is an inaccurate term. You're not really cleaning them. You are offsetting the hashes, till there are no longer any detectable partial pattern matches. Your goal is to make all substrings randomly unique, without visibly breaking the product, nor creating additional trackable patterns. This is done using millions of tiny multidimensional calculus equations on the bit matrix level.
IMVU'S security systems against sex products, are the same security systems that most businesses use to protect against malware. What you have to realize, is that IMVU staff trained an anti-virus like algorithm to find and attack sex product assets, instead of attacking malware. That's how much IMVU staff hates the freedom to love. Therefore, in order to get sex products past security, you have to treat sex product files the same way hackers treat malware files. The same methods hackers use to get malware past antiviruses, are the same methods you have to use to get sex products past IMVU's security against them. That's what our software is really doing for you.
"Dirty" and "cleaning" ... are just slang terms people who don't understand what is really going on under the hood use. Like most popular slang, we have to humor and honor the words in use, to communicate with those using them.
