First of all, sorry for my bad English :tape: im new to blackhat and i found out people here are so helpful and professional in this field, i started to love here :heart: anyway i really need to know how Facebook trace and identify a user even when this user reset their IP constantly and clear cookies as well as private browsing, etc and also how to hide our self from that. i found out that even doing all of this, FB also able to trace us,maybe by Mac Address? Windows Serial? Registry? this can be told when we creating multiple facebook accounts. no matter i reset new IP or clear browser cookies, fb still can trace me and give the god damn roadblock. but my purpose is not opening accounts i don't need them, by knowing how FB trace me, it can greatly reduce my risk of getting blocked when i tag a photo(im a retailer who use a lot photo Tagging functions). Im really looking forward masters here can help me out in this, I BEG FOR YOUR HELPS! i spent almost a weeks to research for this but i couldn't find much helpful tips. if i keep on failing to find an answer here, i think ill end up closing my business... and find another job....:frown: anyway thanks for you guys time, god bless everyone here.
