Hydra -Gtk Stops Attempts on First Server

Hi every1,

I'm trying Bruteforce attacks on MY OWN FACEBOOK PROFILE and I have created a password list. I'm also trying smtp and xmpp protocols. I have set the maximum number of tasks running in parallel to 64, when I start the attack it only tries the first 64 password . Does any1 know a solution to this ? A friend told me I'm getting banned

I know it may seem a stupid question, I'm just getting started
