Here's an idea that has been tossed around, maybe you missed it, maybe you are working on it, I don't know.
Ever think about setting up a simple word filter for searching, such as, "gil" and "Omgwtfbbq?!?!?!?!" Much like what google has on their search engines now a days. My brother said he could set on up in a matter of minutes with the right tools. I wouldn't know how to do that if even if you spelled it out for me, so don't take offence if I sound arrogant.
Sorry if this has been mentioned 1000 times.
