A chashuve Yid told me that his father had an unfiltered computer at home. His children spoke to him and tried convincing him to install a filter (especially since there were some family members who occasionally surfed on "not the best places" on their father's computer, r'l), but he refused. He feared that a filter would prevent him from accessing the sites he was accustomed to accessing. (This is a fear that many have, but it is generally unfounded. Whatever one needs, he can easily get to, even with a filter.) This man had many grandchildren who were waiting for shidduchim. The person who told me this story had a twenty-four years old son, who was having trouble finding a shidduch. The grandchildren asked their grandfather that he should set up a strong filter, and perhaps in that merit, Hashem will perform chesed with them, and they will get engaged.
On the 15th of Cheshvon, this year (5786), their grandfather said that if, within forty days, one of them gets engaged, he would install a filter. They wrote up a contract. On one side of the page were the names of all the older grandchildren, and on the other side was the grandfather's promise that if one of them got engaged within forty days, he would filter his computer.
With Hashem's help, on the fortieth day, the twenty-four-year-old bachur got engaged. It was hashgachah pratis that the shidduch was finalized on the final day. The girl was from another country. The girl's family wanted to push off the engagement for the next day, but since the bachur and his family had already scheduled their return flight, the girl's family agreed to make the engagement a day earlier – on the fortieth day of the kabbalah!
