I mostly mentioned HtmlPurifier as a counter to strip_tags. Obviously,
it's of little use together with Lua.

I always get a little uneasy, whenever people talk about filtering
HTML. Mind you, there are situations where that's the only thing to
do, but generally speaking, you have a security problem, the moment
you let the user supply data, that you are going to display directly.
Filtering helps, but it's fundamentally a flawed solution. Just my 2€.
