MAC is not given to any website, it is only known locally in your LAN for other purposes. Websites can identify you by IP address, User Agent, referrals and footprinting
Ahhhh, perfect. Many thanks for the help.As long ad the accounts have been made via resedental ip address ,your be fine .... the proxies your using for the account must be in the same country.
VPN would do something about thatnot true.....i`m 100% percent sure fb and g can see mac addresses and use it in their antispam algos....there are few case studies here on bhw about this subject. Mac address is so easily leaked that it would be a no brainer for them not to use it in their algo. I will take it a step further....I believe fb started to use first network node info aka ur router in their antispam algo. u can change ur ip u can spoof ur mac but u can`t do shit to ur router.
