starting to cloak on fb will lead to your accounts going down pretty quick, , espicially if your running in tier 1 countries and are new to the cloaking game. So make sure you have a more than 1 as a back up. I would suggest about 5 to 10 as they will go down like flies if you don't know what your doing.
Also try and avoid tier 1 as much as possible when learning as again, these markets are saturated and very monitored by FB so they tend to be alot harder to get things moving if you don't know exactly what your doing.
