Some of the problems....
Gilui Arayos - Even so-called "religious" websites constantly feature articles and links about news stories related to disgusting behavior. No practical benefit. All it does is pollute peoples minds.
Sheker - Someone sent me from an article that reported the disgusting מוציא שם רע said by a kiruv activist about those killed by the Nazis. [Can't repeat it...]. So much sheker.
Bittul zman and bittul Torah - People waste thousands and thousands of hours on UTTER NONSENSE.
So much more.
Sweetest yidden brothers and sisters!!! PLEASE stay off as much as you can and invest your time on worthwhile pursuits.
Bi-ahava rabba and good shabbos,
Me
