In the last few days there has been some concern that some if not all the major social networks have been using this type method to detect a Bot, or social poster. Even sites like CL could be if not IS using what's called Device Fingerprinting. I know for a fact that most credit card processing companies are using this for detect fraud. With Device Fingerprinting you can change your IP, MAC address and browser all you want, they will still know who you are. Even wonder why when you post on CL and your ad gets ghosted? You spin like hell, change ip's, accounts and still nothing, well this is why. With FB they would be able detect that its YOUR PC or Remote Server that's spamming them. You can use 1000 accounts, change your IP's or use Beans as your IP source, clear your cookies, spin your ads, use 1000's of Sort Urls, even change your MAC and they will still know its YOU! Scary isn't it? Are they using this technology now? They would be stupid not too.. Here are some sources and interesting reads.. I cant post links on here yet.. So what you will need to do is GXXgle this>> "myyearbook-moves-to-the-head-of-the-fraud-prevention-class-using-the-threatmetrix-fraud-network" Also GXXgle this>> "threatmetrix-announces-cookieless-device-identification-to-prevent-online-fraud-while-protecting-customer-privacy" The Wall Street Journal also has a writeup on this but how to prevent it.>> "how-to-prevent-device-fingerprinting" You can read more about how the system works here>> "Device-Fingerprinting-and-Online-Fraud-Protection-White Paper" Now This is where the FTC steps in to save the day, or will it? They want these sites, to have some sort of Opt-Out option, where they will not be allowed to collect this type of fingerprint from your device.>>> "FTC Backs Do-Not-Track System for Web" Hope this info helps some of you guys out and be careful on what you do BH! Will like to read some of your input on this... Have a nice Day..
