And people wonder why we sometimes look askance at the future of the human race.
The nonprofit Epilepsy Foundation, which runs the forum, briefly closed the site Sunday to purge the offending messages and to boost security.
"We are seeing people affected," says Ken Lowenberg, senior director of web and print publishing at the Epilepsy Foundation. "It's fortunately only a handful. It's possible that people are just not reporting yet -- people affected by it may not be coming back to the forum so fast."
The forums have been restored. It should be noted that the U.K.'s version of the EFA, the National Society of Epilepsy (NSE) faced an identical attack last weekend.
