Wow Roku, you really, really need to figure out a way to stop this spam, even if it means forcing people to wait a day or two to be verified before allowing posts. Wading through 3 screens of university spam is insane!
We've already implemented measures to combat the spam. This past incident which you were referring to is an isolated incident, and hasn't happened in weeks now.
Please see this thread
regarding the measures thus far taken.
