YEAH ITS ON!!! THEY just started suspending accounts like CRAZY!
I assure you my account were HEAVY on value. I actually had zero "money-making" intent with them at this point. I simply shared extremely valuable information that I personally love! I mean... just AMAZING value posts. I was proud of them.
So they're suspending across the board anyone who has more than one post, that's the only way I can explain it.
This is definitely in response to the 30DC as they created a new page today:

I'm pretty sure this didn't exist before yesterday as I did heavy research on their terms of use etc...
