Spam, drones and proxies • simple spamfilter with underscore doesn't work

Hello there,
I've a little trouble with a spamfilter. The spammer can be detected with the following string: Julia_nxde and he sometimes put spaces between letters.
So I initialy make a spamfilter on *J*u*l*i*a*_*n*x*d*e*
Trouble: someone has triggered it by saying

J'ai mis les deux erreurs complètes dans le post, si jamais ça c/c une des deux, ils tomberont dessus.

And yes, all letters are in the sentence in the good order, but there is no underscore.

So, I thought I've to double the underscore, as it has to be done in the reason when you want to display one: *J*u*l*i*a*__*n*x*d*e*
But a few hours after, he can come and spam.

So, do I have to use a regexp ? Or is there something I don't understand with underscore ?
