Pro Sites-Unfiltered HTML..safe?

Hey everyone!

I remember about a year ago I was considering offering network admins on a network the permission of "Unfiltered HTML' in order to allow them to embed videos from adult sites

I was told this was very dangerous and I should never let normal users have this ability. So I gave up the project. Recently, I have been trying to redo the project but again ran into this barrier without a way out.

However, today I noticed that the Pro Sites plugin offers the ability to give certain levels of users the ability of Unfiltered HTML.

Isn't this still dangerous? Are you assuming users who pay are less likely to be up to no good? I really really want network admins to be able to embed videos and it drives me crazy that they can't.

Is it possible to provide unfiltered html with also being able to put in safeguards to prevent the dangerous stuff?
