Another panel question

Hello There
i see a lot of panel selling real followers ( ads)
My question is : are those followers real or they are just fake account ?
i'm looking to growth my account ( have 6k followers and 14% engagement )
i try to raise to 10k ( like this i can put links on stories) but don't have a lot of money to spend on this...f/unf don't work cause when i unfollow account , the account also unfollow me and i also receive a lot of ban with that technique so i try to find a solution
thanks for reading...and for your help

most likely they are fake cause its from panels but u can always try a review copy and test it yourself
