HI
yes, u can make multiple fb account from same computer, same IP.. no problem.
But u may need mobile verification to make the account stable. and also you must use it regularly. update profile, add friends and others.. just like a fb user doing all the time.
There are many school and university at usa running total computer network under 1 ip routing.. and even oxford university running under same ip address for all their students pc. using same server and router. SO, just forget those trick and tips.
fb not bann account if you NOT over flow the account by spam or fake advertisement.
another big error marketers making is, verifying fb account with other countries phones...
if you use usa or uk account and use asian countries mobile number then fb will kick your account sooner or later..
even u remove the phone number after verification, they always keep record of it and they never forget about it.
just use fb account as all other using.. there is NO problem with it.
thank you
