Is there anyone that can explain the Andy Sixx spam to me? Just now there were, I shit you not, 11 threads on /b/. Eleven. Are the mods fucking with us?

I'm using 4chanx and I don't know shit about regular expressions. I actually posted here a while back about it and got some expressions, but not one of them worked, at all.

Honestly, I'm probably not going to bother renewing my 4chan pass this time.

Can anyone make sense of this for me?
