WHAT "ramifications"? A few unfounded nusiance lawsuits?
"Nusiance" lawsuits are expensive. One still gets to retain an attorney with his billing hours. A few "nuisance" lawsuits could shut down this site, win or lose. I suggested this very idea a few years back, but then had the whole legal aspect explained to me. As is it would be hard to hold the site liable for the opinions published here. If they were a part of the site controlled directly by the site it's another thing again. If Spark thinks that's not a problem or is willing to entertain a few dozen "nusiance" lawsuits more power to him.
