Technorati ignores my tags

It's being some days now, some of my blogs are no more indexed by Technorati. As a matter-of-fact, Tecnorati won't even accept pings for these blogs. Whether they are given from a ping service or directly through a Tecnorati "ping now" button, the result is the same. Nothing!

What is really annoying is that I've built a feed upon a Technorati tag of mine, and this feed is now half-filled!

I'm searching the issue.
