What do you mean by "block" them? It's your choice to choose which Personas you want. Unless you are talking about reporting an inappropriate Personas, then go to this forum for help:

To whom it may concern,

I just received an email from your Personas Team telling me my Persona was inappropriate. I must disagree!! I am a Grandmother & a Great Grandmother!! I do not, & have never submitted anything I felt was inappropriate!!

Before I created my own Persona, I looked through thousands of your Personas & there are many that are sexually suggestive with Men & Women that are 'almost naked'!!

So, I made two Personas, both of which I realized had my oldest Son shooting the "F" finger, or the bird. I deleted these first two thinking there might be an issue. But was anyone in my Persona NUDE? NO!

I also made sure to check your 'little box' to not make it public. This was to be ONLY for my eyes & no one else!

I then made a new one & even renamed it. No one is half naked & nothing is inappropriate with this new Persona!! I will try one more time to submit the last one I made. If you send another email like this one I've now replied to, I AM THROUGH with Personas!

My new one is named "My Kids & Grands", which I have also deleted because there is definitely a problem with your Team! They have either not recognized my deletion of the first two, or they have mistaken the renaming as someone's Persona.

Dendy,

This in not the forum to discuss that issue. No one here works for Mozilla, we're all volunteers helping other Firefox users deal with Firefox issues. None of us here have any "sway" with anything to do with Personas issues or policies.

If you don't agree with that decision, this is a more appropriate forum to attempt to try to find out why your Persona was deemed inappropriate. http://groups.google.com/group/mozilla-labs-personas

What I mean by block is stop the image from being seen. For instance, I use K9 Blue Coat Web Protection and can choose to have open media images that I consider inappropriate to not show up at all. Is there any way to do this with personas?

You have to choose and "wear" that Personas before it'll be shown on your browser. If you are talking about blocking them in the gallery of Personas, I don't think so.

But I might be wrong. You might want to try post this question in Personas' forum. They might have a better answer for you.

Thank you! I'll do that!
