From the article:

"surveyed 800 habitual online smut viewers and found “excessive users had severe social and relationship problems and had often lost their jobs or been in trouble with the law as a result of their addiction."

This is questionable science. In the first place how were the subjects selected? I find it hard to believe that a truly representative sample population could be obtained since I wouldn't expect that many smut viewers without problems would volunteer to be studied.

Second the conclusion apparently being drawn is that excessive viewing of smut results in severe social, relationship, and employment problems. It is just as likely that having such severe problems resulted in the excessive smut viewing as a distraction from reality.

This kind of bogus science shouldn't be taken as gospel. Sometimes scientists have personal axes to grind just like laymen.
