I will try it out and of cause, if it doesn't work, I will reply here. From your description, I believe it will do the trick that I have sought after.
Thank you so much for the assistance.
Cheers.

create a group and named it as Banned and move all the banned users to the group
then you can make the custom block only viewable by the banned group in the group setting
