I did some research this morning and it looks like at one point a potentially malicious Flash file attempted to make a DNS request to this domain during analysis. Users of exploit kits will often compromise sites like this and use them to deliver malware to "victim" browsers. Often on the these forums the vulnerabilities are found in poorly developed plugins like Java based photo galleries. Site looks clean to me now, but an Admin should do a once over and make sure all third party libraries employed by this site are updated and patched or disabled.
