Now it is the other way already, some changes just made.
Well, you need to be careful when posting in post count enabled sections, any spams will result your account to be suspended.
This doesn't mean that you can spam on post count disabled sections because we take spams seriously.

As goldfries mentioned earlier, we are in the midst of making some changes.
We received too many reports on Mobile Phone section, hence we need to come out with solution to prevent spamming.
Anyway, as I have mentioned earlier, we take spams seriously even if the section is post count enabled or disabled.
