bisa. contoh:
add dulu akses listnya:
Code:
/ip proxy access add dst-host="*facebook*" action=deny comment="fbpunya"
bikin schedule untuk ngeblock:
Code:
/system scheduler add name="fb-off" start-date="Jan/03/2009" start-time="06:30:00" interval="1d" on-event="/ip proxy access set [/ip proxy access find dst-host="*facebook*"]" disable=no
/system scheduler add name="fb-on" start-date="Jan/03/2009" start-time="20:01:00" interval="1d" on-event="/ip proxy access set [/ip proxy access find dst-host="*facebook*"]" disable=yes
semoga membantu
