i will not be able to point out what is the real reason behind it but as a fellow newbie i can give you some advice that you could apply to prevent being disabled again in this site/group.

keep reading, take time to read the updated rules and stuff. as what i've read a few days ago, the site is implementing new things already to prevent having "trash post" or any kind of post that doesn't have any value and just want to raise their activity counts. also thru reading you can learn a lot of stuff that you could share as well in forum that could possibly help other newbie like us. be thoughtful and think first before you try to do/post something.
