You're showing as level 36 to me.

Currently you're showing as having made a total of 8 posts, were any of those new threads or just replies to others, you're limited to 5 in any 24 hour period on the forums where throttling is implemented.

This one of course is one of those exempt so if you've mainly posted here then .. hard to say. It's clear why SE decided to put in some sort of throttling, it is thought far to Draconian and simply stifles discussion in the very noticeable absence of any real input from SE itself.
